I love Kristan Higgins as an author and wait anxiously for her new books to come out. I admit I was taken aback when I started this one. For one thing, it's written in first person, alternating between two sisters, very different from most of her other books. I adjusted and read on. There were the laugh out loud funny moments that I expect from a Higgins book and a lot of very sad moments too. 
 I adjusted again and thought about it. This is more of a chick lit book which is fine. The writing is excellent and the characters fascinating, warts and all. I stayed up until 4 am reading, then finished it today. 
 Jenny and Rachel both grow a lot during the course of the story. Jenny has just gone through a divorce though she has a relationship still with her ex that is a bit weird. Rachel has the perfect life with her perfect husband, house, and three adorable girls --- until she finds out he's been cheating on her. I found that I cared a lot about these women and the relationships involved. I cheered for them by the end of the book though it wasn't the ending you normally get in a Higgins book. I can't wait for the next book in this series.
