Amadi and the Phoenix
Volume One of the trilogy. Amadi hates being a girl. She manages to become apprenticed to a thief where she lives as a boy. But when her Helping Hand is murdered, her oath of revenge lands her smack dab in the path of an assassin hired to kill her and a jackal-headed god with the same purpose. Now, her only defense is the threadbare tunic of a young man and her training as a thief.
