"The Dream Stalker" has everything you could want in a mystery novel -- a suspensful and compelling story, well-drawn characters and setting, an intriguing glimpse into the Arapaho culture and frustrated love.
About the only complaint I could make is I wish Margaret Coel would continue the stories of her supporting characters from novel to novel. For example, her last book ended with Susan, Vicky Holden's daughter, in drug treatment. In "The Dream Stalker," it is mentioned Susan has returned home to L.A., but nothing else is stated about her recovery or her strained relationship with Vicky. Coel is so good at making me care about her characters, I want to see what happens to all of them.
However, that's a small quibble about a series that is rapidly becoming one of my favorites.
I also want to note the villain in "The Dream Stalker" was one of the most chilling killers I've ever encountered in mystery fiction, a person made all the scarier because of their absolute conviction that what they are doing is justified.
