Beneath the surface of our world, mythological creatures and their artifacts still exist—corrupt people pay fortunes for a sliver of dragon bone, a basilisk's scale, or an angel's wing. Angela Gough is an American criminology student in London whose fiancé Vince disappears, and her investigation leads her into a black market specializing in arcane relics. She meets Mary Rock, a criminal of mythic status who also wants to find Vince… to kill him. Angela and a growing team of adventurers must stop this horrific trade, yet they face a growing menace as the hunted creatures begin to fight back.
