The first volume in Rebecca Yarros' popular Empyrean series. From Amazon: Twenty-year-old Violet Sorrengail was supposed to enter the Scribe Quadrant, living a quiet life among books and history. Now, the commanding general-also known as her tough-as-talons mother-has ordered Violet to join the hundreds of candidates striving to become the elite of Navarre: dragon riders.

But when you're smaller than everyone else and your body is brittle, death is only a heartbeat away...because dragons don't bond to "fragile" humans. They incinerate them.
