This book is a sort of sequel to Black Lands, which I raved about, but it was not in the same league. It's not a bad book, far from it but it seemed disjointed to me and I'd guessed who the killer was by the half way point - it starts out very well but it's nowhere near as dark as Black Lands and on times trends in cozy crime territory. And that to me was a problem when I was reading - I like cozy crime but this story seemed to want to be dark psychological thriller and cozy crime at the same time and I just didn't find it as compelling as the other books I've read by the author. There is a another book that follows on from this one, Finders Keepers and I'm starting that one immediately, but only because I know how good the author is having read two of her other titles. If Dark Side had been the first book I'd read by this author then I probably wouldn't contimue.
The next book, containing several of the characters carried over from this one, should be interesting particularly knowing what I know about them from reading this one.
