This is the second book in the Mercy Thompson series and it was deliciously good. Mercy's vampire friend Stefan asks her to be a witness for a message he must deliver to a visiting vampire. This new vampire isn't your typical vampire and has a demon inside him. The vampires, werewolves and fae need this killer contained and Mercy may be the only one to stop him. The story was action packed and the romantic triangle between Mercy, hunky Alpha Adam and the good Dr. Sam..hand me begging for more.
I give this book 4 cups of coffee out of 5
