Out of the Blue

I don't think I've ever read a book that I simultaneously loved and hated at the same time up until this one. I absolutely adored this book up until the end, I really disliked the ending, I understand the importance of being your own person and not needing to rely on someone you love and make your whole world about them but c'mon now they don't get to be together at all?? I get that Sean can visit crest out in the ocean but that's it?? It's just makes me sad that their love will eventually fade into nothing because all Sean can do is visit sometimes and they can never truly be together ever again
