Astrid Holmes is a sensitive who works in the "Freak Squad" for the Chicago Police Department. Her job is to sift through the energies that otherworlders or OW give off. She works with a number of other otherworlders including a banshee, imp, shifters and her own partner, a vampire. Her newest case sends her to the Casino Merveileux, a casino ship docked on the Fox River, to investigate a murder, not knowing that soon she would be facing a LYCAN UNLEASHED.

The investigation has barely begun with Mac, a banshee, and Kurt Jarvis a very jumpy imp, when the Otherworlder Enforcement Agency (OWEA) arrives and her heart sinks when she hears the voice of Mason Sanderson. The very man who not long ago kissed her senseless then said it was a mistake and moved on. When the lights go out in the evidence room and a prime piece of evidence is found missing, she is suspended. Furious, she does the only thing she can do. She goes to Mason and lies to him to get him to let her help.

Mason has a number of reasons to not let her help but the fact that she says she can sense the killer is a plus for him. The down side is the attraction he feels for her but his past is holding him back. As they work together, dealing with the very powerful Luc Chevalier, Magister, (vampire leader) and owner of the casino, the man's son, the victim's widow, they must also deal with the growing attraction for each other. By the time they work through the maze that the case has become Mason learns just what he can and will do to protect Astrid.

LYCAN UNLEASHED is fabulous! The action starts with the first page and is non-stop to the explosive ending. There are a number of twists and turns that keep the main characters on their toes as well as the sorting through the emotional baggage they both carry that will keep the readers enthusiastic attention. The author [Tiffany Allee] writes a story that is believable and thrilling even set in a paranormal world. I very much want to see more along this line from her.
