Let's solve this logic puzzle step by step using the clues provided. We need to determine:

- Which student is reading which book
- The genre of each book
- The due date for each book

We have four students: David, Jordan, Kai, Maggie
Four books: Imaginary Borders, In Other Lands, The Book Thief, The Diviners
Four genres: Historical, Mystery, Non-Fiction, Sci-Fi/Fantasy
Four due dates: November 21, November 30, December 5, December 12

---

Step 1: List all clues

1. The four students are Jordan, the one reading *The Book Thief*, the one reading a Sci-Fi/Fantasy book, and the one with the November 21st due date.
2. Kai is not reading the Non-Fiction book.
3. David’s due date is before the due date for the Historical book but after the due date for *Imaginary Borders*.
4. Maggie is reading the Mystery book.
5. Kai’s book is due either on November 30th or December 12th.
6. The Non-Fiction book is *Imaginary Borders*.
7. *In Other Lands* is due before the Historical book but after Maggie’s book.

---

Let’s process these clues one at a time.

---

Clue 6: The Non-Fiction book is *Imaginary Borders*

So:
- *Imaginary Borders* → Genre: Non-Fiction

---

Clue 4: Maggie is reading the Mystery book

So:
- Maggie → Genre: Mystery

Therefore, Maggie is not reading *Imaginary Borders* (which is Non-Fiction), so she is reading one of the other three books.

---

Clue 2: Kai is not reading the Non-Fiction book

So Kai ≠ *Imaginary Borders*

Thus, Kai is reading one of: *In Other Lands, The Book Thief, The Diviners*

---

Clue 5: Kai’s book is due either on November 30th or December 12th

So Kai’s due date ∈ {Nov 30, Dec 12}

---

Clue 1: The four students are Jordan, the one reading *The Book Thief*, the one reading a Sci-Fi/Fantasy book, and the one with the November 21st due date.

This clue says that the four students can be identified in four ways:
- Jordan
- The one reading *The Book Thief*
- The one reading Sci-Fi/Fantasy
- The one with Nov 21 due date

That means:
- These four identities are all different people, because they're listed as the four students.

So:
- Jordan ≠ reader of *The Book Thief*
- Jordan ≠ reader of Sci-Fi/Fantasy
- Jordan ≠ person with Nov 21 due date

And similarly:
- Reader of *The Book Thief* ≠ reader of Sci-Fi/Fantasy
- Reader of *The Book Thief* ≠ person with Nov 21 due date
- etc.

So all four categories (Jordan, *The Book Thief* reader, Sci-Fi/Fantasy reader, Nov 21 due date) are assigned to different students.

---

Now let’s look at clue 3:

Clue 3: David’s due date is before the due date for the Historical book but after the due date for *Imaginary Borders*.

So:
- Due date: Imaginary Borders < David < Historical

Let’s denote due dates in order:
- Nov 21 < Nov 30 < Dec 5 < Dec 12

So we can say:
- Imaginary Borders due date < David’s due date < Historical book due date

So David cannot have the earliest or latest due date — he must be in between.

Also, *Imaginary Borders* must be earlier than David, and David earlier than Historical.

So possible sequences:

Let’s suppose:

| Due Date | Book |
|----------------|--------------------|
| Nov 21 | Imaginary Borders |
| Nov 30 | David |
| Dec 5 | Historical |
| Dec 12 | ? |

Or:

| Due Date | Book |
|----------------|--------------------|
| Nov 21 | Imaginary Borders |
| Nov 30 | ? |
| Dec 5 | David |
| Dec 12 | Historical |

But David must be after Imaginary Borders and before Historical.

So possibilities:
- If Imaginary Borders = Nov 21, then David ∈ {Nov 30, Dec 5}, and Historical ∈ {Dec 5, Dec 12} — but David must be before Historical, so:
- David = Nov 30 → Historical = Dec 5 or Dec 12 → OK
- David = Dec 5 → Historical = Dec 12 → OK
- David = Dec 12 → no room for Historical later → invalid

So David cannot be Dec 12.

Similarly, if Imaginary Borders = Nov 30, then David must be after that → David ∈ {Dec 5, Dec 12}, and Historical > David → Historical = Dec 12 → only possibility.

But then:
- Imaginary Borders = Nov 30
- David = Dec 5
- Historical = Dec 12

Is that valid? Yes.

If Imaginary Borders = Dec 5 → then David > Dec 5 → David = Dec 12 → Historical > Dec 12 → impossible (no later date). So invalid.

So Imaginary Borders cannot be Dec 5 or Dec 12.

So Imaginary Borders must be Nov 21 or Nov 30

Let’s consider both cases.

But from clue 6: *Imaginary Borders* is Non-Fiction

So the book *Imaginary Borders* has genre: Non-Fiction

And from clue 4: Maggie reads Mystery → so not *Imaginary Borders*

So Maggie ≠ *Imaginary Borders*

Also, from clue 2: Kai ≠ Non-Fiction → Kai ≠ *Imaginary Borders*

So who can read *Imaginary Borders*?

Students: David, Jordan, Kai, Maggie

Kai and Maggie can't → so it must be David or Jordan

So *Imaginary Borders* → David or Jordan

Now back to clue 3:

Imaginary Borders < David < Historical

So David must come after Imaginary Borders

But if David is reading *Imaginary Borders*, then his due date = due date of *Imaginary Borders*, so he cannot be after it.

Contradiction.

Therefore, David cannot be reading *Imaginary Borders*

So *Imaginary Borders* must be read by Jordan

Because only Jordan left among David, Jordan, Kai, Maggie who could read it.

Wait: Kai and Maggie can't (clues 2 and 4), David can't (because of clue 3), so yes:

→ Jordan reads *Imaginary Borders*

And *Imaginary Borders* is Non-Fiction → Jordan’s book is Non-Fiction

So:
- Jordan → *Imaginary Borders* → Non-Fiction → due date: ?

From clue 3: Imaginary Borders < David < Historical

So Jordan’s due date < David’s due date < Historical book due date

So Jordan’s due date is earlier than David’s

So Jordan ≠ Dec 5 or Dec 12 (since David would have to be later)

So Jordan’s due date ∈ {Nov 21, Nov 30}

But David must be after Jordan and before Historical

So possible:

- Jordan = Nov 21 → David = Nov 30 or Dec 5 → Historical = Dec 5 or Dec 12
- Jordan = Nov 30 → David = Dec 5 → Historical = Dec 12

(If Jordan = Nov 30, David = Dec 5, Historical = Dec 12 → OK)

But if Jordan = Nov 30, David = Dec 5, Historical = Dec 12 → works

Can Jordan = Nov 21?

Yes, then David = Nov 30 or Dec 5, Historical = Dec 5 or Dec 12

But let’s see clue 7:

Clue 7: *In Other Lands* is due before the Historical book but after Maggie’s book.

So:
- Maggie’s due date < *In Other Lands* due date < Historical book due date

So Maggie < In Other Lands < Historical

So Maggie cannot be last, and In Other Lands cannot be first.

Also, from clue 1: The four students are:
- Jordan
- The one reading *The Book Thief*
- The one reading Sci-Fi/Fantasy
- The one with Nov 21 due date

These are four distinct people.

So:
- Jordan ≠ *The Book Thief* reader
- Jordan ≠ Sci-Fi/Fantasy reader
- Jordan ≠ Nov 21 due date person

But we already know Jordan reads *Imaginary Borders* → Non-Fiction

So Jordan ≠ Sci-Fi/Fantasy → OK, consistent

Jordan ≠ *The Book Thief* → OK

Jordan ≠ Nov 21 due date → so Jordan’s due date ≠ Nov 21

Earlier we said Jordan’s due date ∈ {Nov 21, Nov 30} → but now cannot be Nov 21

So Jordan’s due date = Nov 30

Then from clue 3: Imaginary Borders < David < Historical

So Jordan (Nov 30) < David < Historical

So David must be after Nov 30 → David = Dec 5 or Dec 12

And Historical > David → so Historical = Dec 12

So:
- Historical book due date = Dec 12
- David’s due date = Dec 5 or Dec 12

But David < Historical → so David cannot be Dec 12 → David = Dec 5

So far:

| Student | Book | Genre | Due Date |
|----------|--------------------|--------------|--------------|
| Jordan | Imaginary Borders | Non-Fiction | Nov 30 |
| David | ? | ? | Dec 5 |
| ? | ? | Historical | Dec 12 |

And *Imaginary Borders* = Nov 30 → matches clue 3

Now clue 7: Maggie’s due date < *In Other Lands* due date < Historical book due date

Historical = Dec 12 → so *In Other Lands* < Dec 12 → so *In Other Lands* due date ∈ {Nov 21, Nov 30, Dec 5}

But Maggie < *In Other Lands*

So Maggie’s due date < *In Other Lands* due date < Dec 12

So possible due dates:

- Maggie: Nov 21 → *In Other Lands*: Nov 30 or Dec 5
- Maggie: Nov 30 → *In Other Lands*: Dec 5
- Maggie: Dec 5 → *In Other Lands*: none (only Dec 12 left, but must be < Dec 12 → no)
- Maggie: Dec 12 → *In Other Lands*: none → invalid

So Maggie cannot be Dec 5 or Dec 12

So Maggie ∈ {Nov 21, Nov 30}

But Jordan already has Nov 30 → so Maggie ≠ Nov 30 → Maggie = Nov 21

So Maggie’s due date = Nov 21

Then from clue 7: Maggie < *In Other Lands* < Historical

So *In Other Lands* due date ∈ {Nov 30, Dec 5}

But Nov 30 is taken by Jordan → so *In Other Lands* due date = Dec 5

So:
- *In Other Lands* → due date: Dec 5

Now David has due date = Dec 5 → so David reads *In Other Lands*

So:
- David → *In Other Lands* → due date: Dec 5

Now remaining due dates:
- Nov 21 → Maggie
- Nov 30 → Jordan
- Dec 5 → David
- Dec 12 → ??? → Historical book

So Historical book due date = Dec 12

Now remaining books:
- *The Book Thief*
- *The Diviners*

Remaining students:
- Kai (only one left)

Students: David, Jordan, Kai, Maggie

We have:
- David: *In Other Lands*
- Jordan: *Imaginary Borders*
- Maggie: ?
- Kai: ?

Books left: *The Book Thief*, *The Diviners*

Genres left:
- Historical → due Dec 12
- Mystery → Maggie reads it (clue 4)
- Sci-Fi/Fantasy → one book
- Non-Fiction → already assigned

Maggie reads Mystery → so her book is Mystery

So Maggie → Mystery

So her book is either *The Book Thief* or *The Diviners*

But *The Book Thief* → unknown genre

*The Diviners* → unknown genre

But one of them is Mystery, one is Sci-Fi/Fantasy

So Maggie reads one of those two, and it's Mystery

So the other is Sci-Fi/Fantasy

Now clue 1: The four students are:
- Jordan
- The one reading *The Book Thief*
- The one reading Sci-Fi/Fantasy
- The one with Nov 21 due date

These are four different people.

We already have:
- Jordan → Nov 30 due date → so not Nov 21 due date → OK
- Jordan ≠ *The Book Thief* → OK
- Jordan ≠ Sci-Fi/Fantasy → OK

Now:
- The one with Nov 21 due date → Maggie (we have her due date = Nov 21)

So Maggie is the one with Nov 21 due date

So in clue 1, “the one with Nov 21 due date” = Maggie

So Maggie is one of the four distinct roles.

Now the four roles:
1. Jordan → Jordan
2. *The Book Thief* reader → someone
3. Sci-Fi/Fantasy reader → someone
4. Nov 21 due date → Maggie

So these four are distinct → so Jordan ≠ Maggie → true

So *The Book Thief* reader ≠ Maggie, ≠ Jordan, ≠ Nov 21 due date person → wait, but Maggie is Nov 21 due date → so *The Book Thief* reader ≠ Maggie

Similarly, Sci-Fi/Fantasy reader ≠ Maggie, ≠ Jordan, ≠ Nov 21 due date person

But Maggie is Nov 21 due date → so Sci-Fi/Fantasy reader ≠ Maggie

So neither *The Book Thief* nor Sci-Fi/Fantasy reader is Maggie

But Maggie is reading a book → and it's Mystery (clue 4)

So her book is Mystery → so not *The Book Thief* (unless *The Book Thief* is Mystery), but we don’t know yet.

But the point is: *The Book Thief* reader ≠ Maggie → so Maggie ≠ *The Book Thief*

Similarly, Sci-Fi/Fantasy reader ≠ Maggie → so Maggie ≠ Sci-Fi/Fantasy

But Maggie reads Mystery → so she can’t be Sci-Fi/Fantasy anyway → consistent

So Maggie’s book is Mystery → so it must be one of the two remaining books: *The Book Thief* or *The Diviners*

But *The Book Thief* reader ≠ Maggie → so Maggie ≠ *The Book Thief*

Therefore, Maggie must be reading *The Diviners*

So:
- Maggie → *The Diviners* → Mystery

Then the remaining book: *The Book Thief* → must be read by Kai

So:
- Kai → *The Book Thief*

Now genres:
- *The Book Thief* → genre: ? → not Non-Fiction (already taken), not Mystery (Maggie has it), not Historical (that’s the Dec 12 book), so must be Sci-Fi/Fantasy

Wait: genres:
- Non-Fiction → *Imaginary Borders*
- Mystery → *The Diviners*
- Historical → ? → the book due Dec 12
- Sci-Fi/Fantasy → ? → the other one

We have:
- *The Book Thief* → read by Kai → genre: must be Sci-Fi/Fantasy or Historical?

But Historical is the genre of the book due Dec 12

We haven’t assigned the genre to *The Book Thief* yet.

But we have:
- *The Diviners* → Mystery
- *Imaginary Borders* → Non-Fiction
- *In Other Lands* → ? → David
- *The Book Thief* → ? → Kai

And Historical book → due Dec 12

Which book is due Dec 12?

We have:
- *The Diviners* → Maggie → due Nov 21
- *Imaginary Borders* → Jordan → Nov 30
- *In Other Lands* → David → Dec 5
- So *The Book Thief* → Kai → due date: only one left: Dec 12

Due dates:
- Nov 21 → Maggie
- Nov 30 → Jordan
- Dec 5 → David
- Dec 12 → Kai

So Kai → *The Book Thief* → due date: Dec 12

And the Historical book is due Dec 12 → so *The Book Thief* must be Historical

But earlier I thought *The Book Thief* might be Sci-Fi/Fantasy

But now: *The Book Thief* → due Dec 12 → same as Historical book → so *The Book Thief* is Historical

So:
- *The Book Thief* → Historical

But clue 1 says: the one reading Sci-Fi/Fantasy is one of the four distinct people

So Sci-Fi/Fantasy reader ≠ Jordan, ≠ Maggie, ≠ Nov 21 due date person (Maggie), ≠ *The Book Thief* reader (Kai)

Wait: *The Book Thief* reader is Kai → so Sci-Fi/Fantasy reader ≠ Kai

But who is left?

Students: David, Jordan, Kai, Maggie

We have:
- Jordan → *Imaginary Borders* → Non-Fiction
- Maggie → *The Diviners* → Mystery
- Kai → *The Book Thief* → Historical
- David → *In Other Lands* → ???

Only David left without genre

Genres:
- Non-Fiction → Jordan
- Mystery → Maggie
- Historical → Kai
- So David → Sci-Fi/Fantasy

So *In Other Lands* → Sci-Fi/Fantasy

Now check clue 5: Kai’s book is due either Nov 30 or Dec 12

Kai → due date = Dec 12 → OK

Clue 2: Kai is not reading Non-Fiction → Kai reads Historical → OK

Now check clue 1 again:

The four students are:
- Jordan
- The one reading *The Book Thief* → Kai
- The one reading Sci-Fi/Fantasy → David
- The one with Nov 21 due date → Maggie

All four are different → yes: Jordan, Kai, David, Maggie → all distinct → OK

Now verify all clues.
