This is the first book in the Riley Jenson (Guardian) series, and also the first book I've read by this author. I have to say it didn't disappoint and is well worth a look.
There's a huge trend at the moment in supernatural fiction thanks largely to authors such as Laurell K Hamilton, Kelley Armstrong and Sherrilyn Kenyon who's female heroines are strong, sexy and more than a match for their male counterparts. Keri Arthur is definitely an author from the same mould. Fast paced books, good storyline, plenty of action and a healthy dose of sex thrown in.
Riley is a mixed breed, genetically half werewolf, half vampire, she is drawn more to the wolf side of her nature, as such she is drawn to the moon and the need to"dance" (ie. have lots of sex) in the week before full moon.
She lives a relatively normal life, office job, boyfriends and brother, but when her brother is kidnapped she is pulled further into the organisation she works for, which works out well for her boss as he's always wanted Riley to take a more active role and take on Guardianship duties.
The book is well written, although I think the author was planning a series from the beginning, rather than a standalone book as there are threads left hanging for future books. I would recommend it to anyone who's already a fan of the genre as a fun read - great for holidays.
