When the illegal organisation Hunters Extreme targets intelligent beings across the galaxy, Kat's lifemate is murdered. Despite being of a pacifist feline-like species, Kat seeks vengeance, only to discover she has murdered the wrong man, the son of an Intergalactic Council member. Pursued by enforcers and exiled from her pride, Kat must kill again to save her life. Aided by a canine-like mystic and a mysterious Agency, she and two young human friends commence a deadly pursuit across the galaxy. To prevent the hunting of intelligent species to extinction, Kat must follow her predator instincts and deny her pacifist culture in a universe of kill or be killed.
