I was in love with this book...for the first 90%. And then it just ENDED. No resolution, not even really a climax. So if you want to be completely hooked, and read amazing stories about four siblings that are heartbreaking and lovely and gutwrenching and happy by turns, definitely give this a try. But go into it knowing that the book itself will break your heart when nothing happens in the last 10-20 pages. Every time I started to read a new sibling's story, I thought "now this is my favorite one of them all." I think Simon is still the one that stuck with me the most, but they were all so unique and intertwined so perfectly. I am glad I read it, for sure; but unfortunately I just can't give it any more than 3 stars.
