Can someone help me find this book?

The book I believe was called "The Beast... Speak not it's name" or maybe just "the beast" and the rest was something of a tag line. it's about a good looking blonde woman who falls for some hot guy from the 4th dimension... she meets him at a party, a jealous ex red-headed lover is involved, there is a professor who is a friend of hers and a psychic and some guy who she has as a friend but he wants more... his power comes from a funky flower that drains hers... that's all i remember... if someone could help me find it that would be great. maybe even e-book form
