Keira Blackwater is human. She owns a classic car shop, hangs out with her two best friends, and goes clubbing on Friday nights. Her life is pretty typical for a twenty-two year old living in a world where supernaturals live out in the open. Except for one little thing...her blood. It alone has the ability to cure the virus that created supernaturals hundreds of years ago after the Great plague, and make them human again. She's accepted what it can do, and aside from her phobia of sharp, pointy needles, doesn't think about it too often. But then her blood goes missing from the local hospital, supernaturals start turning up dead with a strange anomaly in their system, and Keira is blamed. Vampires and werewolves suddenly hunt her at every turn, and not because they want the cure. As Keira fights to prove her innocence and track down whoever is responsible, she must come to terms with the staggering truth about her birthright, all while trying to protect the people she loves the most. Will she be able to prove her innocence before time runs out? Or will she lose everything she's worked so hard for...maybe even her life.
