There's much to like about this debut novel, but I was never convinced by the basic premise and didn't feel emotionally connected to the characters or the events. Perhaps if there had been more mystery about what actually happened during the blizzard, it might have been more engaging, but it's completely obvious from the start that (view spoiler)[the babies were switched (hide spoiler)], so there's really no drama. 
 As a character study, though, the book mostly succeeds, as the events of that one fateful day drive everything that happens afterward. We see the impact on the various characters and how their lives are changed, for better or for worse. 
 I did enjoy the book, but felt distanced from the characters somehow -- maybe because almost all of the events in the book, even the ending resolution, are telegraphed way in advance. A touch more urgency or sense of discovery would have helped a great deal. 
 I received a review copy of this book via NetGalley. My full review is posted at Bookshelf Fantasies.
