Something about this book just didn't click for me. I'm not sure why but I realized about halfway through that I could put the book down and walk away and probably not miss it/want to know the ending. Not a great sign. I think I had the most issues with the way the book was set up- alternating between the present day and a summer twenty years previous. The time periods would alternate and it was never totally clear which version of Olivia, the main character, I was reading. Even towards the end, I would still have to piece together which Olivia I was with. And that kind of made the reading experience less great. 
 I will say that the author handled and showcased living with a mental illness (bipolar disorder) rather well and the illness was never handled lightly. Some books add in a mental illness to have a character seem quirky or show how love can save someone with an illness (gag). So I was very happy to see that bipolar disorder added to the story in a meaningful way and was handled very well and intelligently. I have never experienced bipolar episodes personally but from the research I've done and the people I know with the disorder, I could tell that this was pretty faithful to real life experiences.
