The One (by John Marrs)

Speculative fiction about a world where DNA can tell you your "perfect match." Marrs introduces five characters and shows how their matches unfold. Twists and turns ensue.

I read a review that said "once you pick this up you won't be able to put it down" and indeed, I picked it up and couldn't put it down until I knew how it ended. Stayed up way too late reading, but who doesn't love that experience? I think Gone Girl was the last novel that happened to me with.

The writing is flawed, some stories are better than others (Nick's is the best) but I had to keep turning pages to find the next twist and surprise.
