I'm a sucker for quirky love stories that involve improbably relationships with time - such as "The Confessions of Max Tivoli" and "The Time Traveler's Wife." I was hoping I'd add this to that collection, but for me it fell flat. There were promising elements - the condition, the society, the quest to find a lost daughter, the sense of history, etc. Overall perhaps the problem was that there were TOO MANY promising elements. It felt like a hodgepodge of possibility, with no one thread developed into something satisfying. Still, I'll check out another book by Matt Haig because he's not a bad writer - I think he may have just been overly ambitious with this one.
