Started out very strong, and I found Preston intriguing. Half-way through, however, the characters started blurring together and the typos got very distracting. Typos and flat-out mistakes, that is. (It's "GoodFellas," not "Good Fellows.")
Anyway, I was horribly disappointed in the ending. Preston was just about the only fully-realized character (a Pepsi addiction does not a character make, in regard to the main detective).
My disappointment at the (way too pat) ending was made bitter by how excited I was by the beginning. I took the book off my Kindle.
