Undone was a sweet, easy beach read. I didn't really get overly attached to any aspect of the book. Brendan and Paige were a cute couple. The secondary characters gave a little something extra to the story. The town itself was probably the most interesting for me, but that is probably because I grew up in a small town where everyone knows everyone's business like that. I wish a couple of the story lines played out more though. They could have added a little more oomph to the book. I do think the series as a whole has potential though.
Nevertheless, it was a good filler read when you need a break from the want to bash the ipad/kindle/nook on someone's head reads.
