Jade Evans learns just how problematic it is to have a somewhat dark past when the Dementors - soul-sucking, happiness-leeching creatures from the wizard prison of Azkaban - become a daily part of Hogwarts life. Plus the constant danger of murderer Sirius Black, and the creepy black dog that keeps showing up everywhere.

Jade Edwards was an ordinary girl with no parents, living in an orphanage. Then the strange man appears, and before she knows it she's living in a magical school, is definitely not ordinary, and - strangest of all - she's managed to land herself a father. Specifically, the dreaded Potions Master, Severus Snape.
