If survival of the fittest was once humanity's anthem, silence now reigns. The Aud have driven humanity's remnants to huddle like mice in their final bastion. In a gamble, a nobody embarks on an impossible mission: time travel. Nine hundred years in the past, she finds herself hunted by survivor's guilt and the Aud who followed. In this pre-collapse world, where humanity's anthem is still survival but the seeds of its coming evisceration wait to sprout, she is alone. Between an apex predator with everything to gain and a human with everything to lose, a race to rewrite human destiny has begun.
