Can't say too much, because I don't know how to talk about what I loved about this without spoilers. I enjoyed myself from the beginning, but once everything started to come together (in the 50-70% mark), I fell in love with what Henry was doing. A lot of that had to do with the character work. I'm a character-driven reader, and it took me a long time to connect with Harriet. As her story unraveled, I realized it wasn't an accidental flaw of the book, but a function of the things she was struggling with. I think the way Henry slowly drew this character out over the course of the book was fantastic. 

In typical Henry fashion, despite the title and beachy cover, this is more of an emotional read than a light-hearted one. It also relies heavily on miscommunication tropes, which I think are handled immaculately, but likely will still bother some people. All pluses for me, but definitely worth noting.
