Jupe rocks, as always. I love how close he and Cady have become especially because of their shared experiences with a shitty parent.
The book coasts along nicely with Lon & Cady hard at work discovering who is behind the robberies in town and then at about the 75% mark, just when you think everything is about to be resolved, WHAM! The whole plot takes a sharp curve and you're left with a OMG! I would say that the ending is a mild cliffhanger. Nothing to get bent out of shape over, but leaving you looking up when the next book will be released.
