    24 Absolutely Wild Differences Between The "Pretty Little Liars" Books And TV Show

    I can't believe Caleb Rivers, the best man in Rosewood, doesn't exist in the Pretty Little Liars books.

    One of my absolute favorite guilty pleasure shows is Pretty Little Liars. It's total chaos, but I can't resist the jaw-dropping mysteries, the ever-changing ships, and the ridiculous plot twists.

    Before there was Pretty Little Liars or Pretty Little Liars: Original Sin, there were the PLL books by Sara Shepard! There are 16 books (plus companion novels), and the differences between them and the TV show are honestly astounding. Here are 24 of the absolute wildest differences between the novels and the OG show:

    🚨 Warning: MAJOR spoilers ahead for both the show and the books!!! 🚨

    Note: Some of the following mention grooming, sexual abuse, and suicide.

    1. First off, the Liars aren't friends in the books — at least, not in the beginning.

    2. Caleb doesn't exist in the books...

    ...so neither does Haleb 💔!

    3. In the books, Ezra and Aria's illicit relationship is short-lived, and he actually ends up getting arrested for dating his underage student.

    ...whereas on the show, they're a main couple, and they even get MARRIED in the finale.

    4. In the books, Aria's biggest romance is with Noel Kahn instead. The two briefly date in Season 1 of the show, but it's nothing like their relationship in the books.

    5. Aria also briefly marries her old boyfriend from Iceland in the books, although their marriage is later proven to not be real. This definitely doesn't happen on the show, although the Montgomery family does spend some time in Iceland before the start of the series.

    6. Noel is best friends with Aria's younger brother, Mike, in the books. On the show, they barely interact.

    7. On the show, Toby is a very important character. In the books, he's only a minor character — and he's not a good guy at all.

    ...so, yeah, Spoby definitely isn't a thing in the books.

    8. Spencer ends up with Wren in the books. Her sister, Melissa, ends up with Wilden.

    9. In the books, Emily is bisexual and has relationships with both guys and girls. On the show, her character comes out as a lesbian.

    10. Also, Emily has a secret baby in the books! Yup, you read that right.

    Teen pregnancy isn't a major part of any of the Liars' storylines on the show. For a while, the characters suspect that Alison was pregnant before her "death," but this turns out to be false. Spencer and Toby also briefly have a pregnancy scare on the show. Additionally, Troian Bellisario revealed on her Instagram story that she actually filmed an abortion scene for Spencer, but it was ultimately cut.

    11. Hanna and her mom are not close at all in the books.

    12. In the books, Spencer is blonde and Hanna has dyed auburn hair. On the show, Spencer is a brunette and Hanna is blonde.

    13. Mike and Hanna get married in the books! On the show, it's revealed that Hanna and Mike had a secret fling a couple of years ago, but it never becomes more than that.

    14. In the books, Mona actually dies for real. On the show, Mona is presumed to be dead in Season 5, and Alison goes to prison for her murder. However, she later turns out to be alive.

    15. Maya does NOT die in the books.

    16. In the books, Emily tries to kill herself and also fakes her death. This is somewhat similar to Mona faking her death on the show.

    17. Although Mona is the first A in both the books and the show, her motives are different in each version. In the books, she becomes A because she saw the Liars blind Jenna. On the show, she's A because she wants to get revenge on the rest of the Liars for "taking her only friend," Hanna.

    18. On the show, Emily and Alison end up together and have twin daughters. However, Emison never happens in the books.

    19. In the books, Aria's mom has a boyfriend named Xavier who acts inappropriately toward Aria. This doesn't happen on the show, but Aria's mom does have a boyfriend (Zack) who hits on Hanna.

    20. On the show, Spencer has a breakdown after finding out Toby is A* and mistakenly believing that he's dead. She subsequently lands herself in Radley. In the books, Hanna is the one who spends time in a psychiatric hospital instead.

    21. Spencer and Alison are half-siblings in the books. On the show, they're eventually revealed to be cousins (through Spencer's biological mother).

    22. In the books, Aria and Mike have a baby half-sister through their dad and his new wife, Meredith. Emily also has three siblings in the books.

    23. Spencer does NOT have a secret twin in the books. Instead, Alison has an identical twin, Courtney.

    24. And finally: Alison is A in the books.
