The first book I read in 2016 was appropriately a Christmas gift. It's not technically a YA, however, the main character is 17, so I'm putting it in that category for my readers.
Uprooted (Del Rey, 2015) by Naomi Novik captured me from the opening sentence: "Our Dragon doesn't eat the girls he takes, no matter what stories they tell outside our valley." This time Agnieszka and the whole village know that her best friend Kasia will be chosen since she is so special. And Agnieszka hates the wizard for that future action. It doesn't matter that he protects them from the Wood. Or that this happens every ten years as payment. But Agnieszka is wrong about what will happen.
The book was hard to put down, and had believably scary monsters. This fantasy will stick with me and I'm hoping the author will write a sequel.
Naomi Novik is the author of another series, the Temeraire novels. I'll have to check them out. Read more about the author and her books at her site.
