Touch of Madness (The Thrall Series)

Kate Reilly is having a bad month
 
She's on trial for murders she didn't commit. She's next on the list of a serial killer. The parasitic vampires known as the Thrall want her to investigate the murder of their young, and will use any means necessary to force her to bow to their demands.
 
And--possibly worst of all--her boyfriend Tom's werewolf pack is trying to break them up so Tom can mate with a werewolf to ensure the survival of his pack.
 
Now Kate must fight for Tom--and fight for her very survival in this brand new paranormal romance from the unbeatable, bestselling team of C. T. Adams and Cathy Clamp.
