** spoiler alert ** 
 I actually didn't like this book as much as I hoped. It was just hard for me to root for someone who was helping someone cheat, even though the relationship was not one that was supposed to be. I did like the character of Rachel and she is very relatable, but Darcy seemed like a caricature of a person. It could just be that I don't know many people like that though, so it was hard to understand her. 
 Overall, it was well written and I enjoyed it, but I just couldn't get over the overlying theme of infidelity. Call me old-fashioned, but I wanted everyone to end up separate in the end because I don't think cheating parties should be rewarded. I'll still try the next book in the series and see where the author takes it.
