A description of this book from the author's website: "The first book in a sexy, humorous paranormal thriller series featuring Aisling Grey, an apprentice Guardian, and her sometimes boyfriend, sometimes foe Drake Vireo, wyvern (leader) of one of the four dragon septs. Aisling finds her true calling when she travels to Paris to deliver a medieval object that is part of a set sought after for the power it wields. There she meets the handsome Drake, a man who is not at all what he seems. Implicated in the circumstances of two murders, Aisling, the demon she summons for help (and subsequently can?t get rid of) named Jim, and Drake find themselves caught up in a web of lies and confusion that could well result in the demon lords of hades ruling the mortal world." This is a fun book to read. It's catergorized as a "paranormal romance". I adored it and will read the entire series. I was initially drawn to the book because the character Jim is a demon in the form of a Newfoundland Dog and he is quite comical. If you aren't familiar with this type of story, don't be put off. The main character, Aisling Grey, is also new to this "world" and so I learned through her. Good Good fun!
