On Friday, "Paper Towns" premiered in theaters. In it, a teenage boy (played by Nat Wolff) goes on a road trip to find popular girl Margo (Cara Delevingne), who mysteriously disappears with only a few cryptic clues as to where she's gone. It's based on the YA novel by John Green, who also wrote the book that spawned last year's hit "The Fault in Our Stars."
It's far from the only bestseller making its way to the big screen this year. Here's a look at the other books getting turned into movies in the second half of 2015:
