After centuries of secret conflict, humans and parahumans have reached an uneasy truce. But unspeakable evil now threatens the tenuous peace.
Teenaged shapeshifters are being slaughtered by a sadistic serial killer who rips their still-beating hearts from their paralyzed bodies. A task force forms to halt the madness, including the vampiric Aeternus Antoinette Petrescu, as well as Kitt Jordan and Raven Matokwe, members of enemy Animalian tribes . . . and forbidden lovers.
A centuries-old blood feud has divided their shapeshifting peoples, and if their passion is discovered it will doom them both. But past hostilities must be put aside, for the killer they seek is but the first sign of the all-consuming nightmare of The Dark Brethren.
