The Hangman's Daughter, Oliver Potzsch - This is a historical thriller set in but it piqued my interest when I saw it at the bookstore. Enjoyed this one a lot, even though it was a bit different from my usual fare.
The 2015 Epic Reads Young Adult Gift Buying Guide. I like how it breaks down these books by genres to give you a better idea what they are about. This could be used for display ideas, and the covers will appeal to the students.
