Plague of Witches — John Patrick Kennedy

Kana thought she had everything, until everything changed...

With her wealthy father dominating her life and no memory of her mother, Kana has grown up bright, beautiful and bent on success. At twenty-one she is about to start her M.B.A. and preparing to join her father's business.

Then Professor White appears bearing a twenty-year-old message from her mother: Kana is a witch. Kana doesn't believe witches are real-who does?-but what Professor White shows her that night makes it impossible not to believe.

Now, Kana is heading to elite Shipton University to study witchcraft and solve the two-decade-old mystery of what happened to her mother. But when she gets there, she will have to face far more than just the past.

Because on the night Kana learned of her powers, something escaped its prison. The entity is hungry, angry, and it wants revenge...
