3 1/2 stars. 
 It enjoyed this well enough, but I was just kinda bored throughout. I called the plot twist VERY early and that bugs me. I really liked the main characters and would have enjoyed getting to the meat of them a little better as well as deeper into the relationship. 
 A good fun 3+ hr read for me. I liked it more than "Breathe" - the first book in the series, but honestly I only read this now because of the very good buzz about the third book in the series, "While It Lasts", which as I write this I'm over 30% done with and yeah, I can see the difference.
