Like my first Jenkins Reid book, The Seven Husbands of Evelyn Hugo, I read this book in one sitting. It's certainly a page turner. I thoroughly enjoyed reading about the development of Emma's relationships with both Jesse and Sam, and I found how Jenkins Reid wrote Emma's dilemma about which man to be with (which was also a dilemma about which version of herself she wanted to be long term) compelling. Love triangles are really hard to write in a non-obnoxious way. I have a low tolerance for them as a rule but I thought Reid did a good job making the audience understand why Emma wavered between the two men, and none of the characters act with malice towards each other. The period of wavering also doesn't go on for too long without resolution. 
 Part of me wants to give this five stars because I did felt such a high level of emotional engagement. My heart says five stars but my head says "Jesse and Sam are a little too unrealistically mature and saintly" and "the ending, while enormously satisfying, is also overly tidy" so I'm going for 4.
