Kaida Nylenoss is the last of her House. Banished and stuck in the Human Kingdom, she has no choice but to make potions and charms for the humans that hate her. One day she'll pay off her debt and have enough money to move to Oneryx, the city of dreams, and she is willing to do anything to make that happen.  But when Aeddan, a strange demon, visits her shop in need of a tracking spell, Kaida finds herself a step away from everything she's ever wanted and everything she's ever feared.
