Linger (Book Review)

I found the book to be a delightful read.  The rewriting of the werewolf thing was a little refreshing.  The book focused more on a scientific view - trying to determine why the shift from human to wolf occurs. I was a little upset because some of the events that occurred in the book were never fully explained.  For example, under what circumstances was the heroine bitten, why was she left in the car by her parents, what happened to the parents of Sam, etc. I smell a sequel.
