Kate O’Connor’s trying to move on from a tragic past, but there’s a big difference between wanting to forget and having someone rip the memories right out of your head. When Kate returns from an unusual courier job with no memory of where she’s just been, alarm bells start ringing. But the weirdness gets seriously out of hand when a werewolf shows up in her kitchen and tries to kill her. It turns out there’s a whole hidden world of shifters out there—and most of them want Kate dead. Shame she can’t remember why. Werewolves are only the beginning of Kate’s troubles. The shifter world is ruled by the dragon queens, and Kate’s managed to land right in the middle of a supernatural war of succession. As the queen’s daughters fight to the death, Kate forms an unlikely alliance with her attacker. To have any hope of surviving she must uncover the explosive secret hidden in her memory—but first she has to live through the night. Twiceborn is the first book in the urban fantasy trilogy The Proving.
