The Young Adult genre definitely upped its game in 2015, adding diversity in terms of main characters and challenging topics. It's nice to know things are taking a step in the right direction, and the books just keep getting better and better.

In addition to veteran writers making great comebacks, some smash debuts came out of 2015 (*cough* Becky Albertalli *cough*), making the genre even more prosperous. We don't even need to mention all the films based on YA books that came out this year alone.

Unfortunately, there were simply too many books to include them all, so here are our 10 favorites, from epic space adventures to sweet high school romances. Scroll through the gallery above!

Honorable mentions:
Red Queen by Victoria Aveyard
The Girl at Midnight by Melissa Grey
Winter (The Lunar Chronicles #4) by Marissa Meyer
Finding Audrey by Sophie Kinsella
