What a beautiful heartbreaking story, I don't even know what to say, I don't even have the words to explain how this book affected me. I loved it I loved it so much, but it broke my heart at least 50 times. It started as a cute story, I was truly enjoying it: Loved basically all the characters from the beginning, loved how it was written (I mean it's Colleen Hoover, so obviously it was really great), but then, then everything changes, this book became intense, like really intense, and I just wanted to protect Sky and Holder from everyone and anyone. It even made me cry three times (when she remembers her past, when they are going to see her dad, and when Karen tells everything (this one hit me hard). I don't even know what to say really. I loved it, and it's one of those books that I'll probably never forget, and don't want to.
