White Tiger Series by Tamora Pierce, Timothy Liebe, David W. Mack

Angela Del Toro receives the Jade Tiger Amulets into her possession - a gift from her uncle, the former White Tiger, Hector Ayala. Disguising herself in a black jumpsuit, Angela takes to the streets fighting crime.

Angela knows pain: her uncle, the former White Tiger, killed, her FBI partner murdered, her career ruined, her mentor jailed. And the hurt is just beginning. Armed with mystical amulets, the new White Tiger demands answers, but will she survive long enough to ask the right questions?
