Guild Assassin (Curse Breaker, #1)

Wendy Magdalena Braca lived in a Victorian mansion under three moons in Jupiter City. But her privileged upbringing falters when after the death of her father and the murder of her mother, she is shipped away to Greenleaf Asylum for Troubled Girls and lived there for years until she is “rescued” by a strange guild that shows Wendy their world; the world of Guild Assassins made up of the Cæcus (normal humans), the Validus (magic-users), and Half-Breeds (demi-gods). In this world, Wendy discovers she is the most special and powerful Validus known to exist, the Curse Breaker.
