Dave's ready to be single. He signs up for an online dating profile where he meets Liz. Liz interprets their relationship wildly differently than he does which is always bound to create conflict. Especially when another person gets involved. I'm sure this is a very interesting story, though I struggle some with Liz clearly being painted as a crazy, delusional person as the author only tells the story from Dave's perspective. Maybe she was, but it certainly sets the reader up to view Liz as a one dimensional person, and not a good one at that.
