White Magic Academy

Rulisa doesn't want to be a good witch. She wants to be a bad witch. But after her second expulsion from a powerful magical school, Rulisa's father sends her packing off to White Magic Academy.
Not only is this school a laughstock in the witch community, her goody-goody-two-shoes death-enemy is thriving there. When you add visits from her con artist father, an assigned friend who won't leave her alone, and the minor matter of assassins from Black Magic Academy, things are looking annoying.
And why, why, why does her death-enemy keep trying to be her friend?
