Kuro is looking forward to returning to school, but he has to pass an evocations exam before he'll be allowed to do so.  Will he pass? Will he survive the attempt? How large will the crater be?

Book 2 Chapter 5 - Dock Day

Living in secret and stealing to eat is a hard life, but it's all Kuro has ever known. Fear and necessity forged him into the finest young thief in the wizard kingdoms. Nobody can hide forever, though, and a run of poor luck lands Kuro in a place where his quick hands and quiet feet count for nothing: Avalon Academy, school of magic.
