Centuries ago, Bronwyn Liddle's best friend, Alys, was murdered by ruthless vampire, Rafe. To take her revenge upon him, she became the very thing she hated. Remy St. John was a member of the Castus Vox, a secret order of white mages responsible for the very fate of the world until a dark artifact granted him deadly, dangerous powers. As punishment for his crime, he was sentenced to ten years as an agent for the Paranormal Sector of the Secret Service. When Bronwyn's and Remy's paths cross as they hunt a new and terrible enemy, tempers erupt, secrets are revealed, passions are kindled and their lives are irrevocably changed. A mysterious monster that is part werewolf, part vampire and part demon is attacking people in San Francisco. Werewolves and vampires are disappearing off the streets by the dozens. After the Secret Service's resident psychic has a vision of Bronwyn murdering a defenseless human, they suspect she is the one behind the attacks. When she's arrested and her true intentions are revealed, she joins Remy to find and destroy the man responsible for making the patchwork monsters. Their investigation leads them into the darkest reaches of paranormal society, and they discover what humans can do to monsters is far worse than what monsters can do to them.
