Book 19: A Quantum Love Story. Don't remember how I found this book but I had enjoyed Chen's book about superheroes. This one is a "How do we get out of the time loop, but also we've grown closer while caught in the time loop...." sort of book. More romance than science, and plausible romance at that, but not really a romance novel per se. I really enjoyed reading this though I wish there was a little more wrap-up to the ending.
