Young-adult books are almost inescapable, even if you haven't visited the teen section of your local library since high school.

Big-budget movie adaptations of young-adult books like Divergent and The Maze Runner come out next year and John Green's bestselling YA novel The Fault in Our Stars was included in many of last year's best book roundups that were otherwise full of adult fiction. It's a genre that readers have realized is not just for high schoolers.

1. Inexcusable Author: Chris Lynch

"I am a good guy. Good guys don't do bad things. Good guys understand that no means no, and so I could not have done this because I understand." Keir Sarafian knows many things about himself. He is a talented football player, a loyal friend, a devoted son and brother. Most of all, he is a good guy. And yet the love of his life thinks otherwise. Gigi says Keir has done something awful. Something unforgivable. Keir doesn't understand. He loves Gigi. He would never do anything to hurt her. So Keir carefully recounts the events leading up to that one fateful night, in order to uncover the truth. Clearly, there has been a mistake. But what has happened is, indeed, something inexcusable.

4. Feed Author: MT Anderson

Identity crises, consumerism, and star-crossed teenage love in a futuristic society where people connect to the Internet via feeds implanted in their brains. For Titus and his friends, it started out like any ordinary trip to the moon — a chance to party during spring break and play with some stupid low-grav at the Ricochet Lounge. But that was before the crazy hacker caused all their feeds to malfunction, sending them to the hospital to lie around with nothing inside their heads for days. And it was before Titus met Violet, a beautiful, brainy teenage girl who has decided to fight the feed and its omnipresent ability to categorize human thoughts and desires. Following in the footsteps of George Orwell, Anthony Burgess, and Kurt Vonnegut Jr., M. T. Anderson has created a not-so-brave new world — and a smart, savage satire that has captivated readers with its view of an imagined future that veers unnervingly close to the here and now.

12. The Unbecoming of Mara Dyer Author: Michelle Hodkin

Mara Dyer doesn’t think life can get any stranger than waking up in a hospital with no memory of how she got there. It can. She believes there must be more to the accident she can’t remember that killed her friends and left her mysteriously unharmed. There is. She doesn’t believe that after everything she’s been through, she can fall in love. She’s wrong. After Mara survives the traumatizing accident at the old asylum, it makes sense that she has issues. She lost her best friend, her boyfriend, and her boyfriend’s sister, and as if that weren’t enough to cope with, her family moves to a new state in order to give her a fresh start. But that fresh start is quickly filled with hallucinations—or are they premonitions?—and then corpses, and the boundary between reality and nightmare is wavering. At school, there’s Noah, a devastatingly handsome charmer who seems determined to help Mara piece together what’s real, what’s imagined—and what’s very, very dangerous. This fast-paced psychological—or is it paranormal?—thriller will leave you breathless for its sequel, The Evolution of Mara Dyer. Amazon Book Description

And then he meets a girl. First as his captive, then his reluctant house guest, Julie is a blast of living color in R’s gray landscape, and something inside him begins to bloom. He doesn’t want to eat this girl—although she looks delicious—he wants to protect her. But their unlikely bond will cause ripples they can’t imagine, and their hopeless world won’t change without a fight. Amazon Book Description
