I enjoyed the story and the characters, and unlike some, didn't dislike anyone much. But there was something that was unsatisfying about the whole book that I've had trouble putting my finger on.
I think it was partly brought on by the structure of the story. We pretty much get the story in Claire's order, growing up with her and Henry, while at the same time, getting a fairly linear story of their adult life together. There comes that point, however, at her 18th birthday where the child and adult stories come together. It was at this point that the story turned for me. It was as if the love story part was over, and Henry begins to die.
After he loses his feet, it's as if there isn't much else left for him but death. He never really recovers from the loss, and doesn't even seem to really try. Why bother if he knows he's going to die within a year? He focuses instead on leaving a legacy for Alba, and sort of preparing Claire for his death.
Is it that the knowledge of the future brings on a complacency?
I guess that despite the beautiful love story, and the interesting aspect of time travel, the overwhelming predetermination just takes away any satisfaction.
It might have been more satisfying if despite the time travel, Henry had actually been able to affect change.
