This book caught completely off-guard. I'd never read anything by Emily Giffin before, and now I want to read everything she's ever written. It was sweet and sad, but still had a satisfying ending without tying up every loose end. Kirby was a fascinating character, as was Marian and Conrad: they all could have easily turned into charicatures (the adoptee, the successful business woman with regrets, the lovable loser) but they didn't. They were realistic and warm and so was their story. Even though the premise wasn't very original, every other aspect of the story was, and in the best possible ways. I loved it.
