This is the story of Claire, who meets a man in the field of her backyard when she is a little girl. He seems to know everything about her, but as she grows up, he knows less and less while she learns more about him. It turns out that he has a genetic defect that causes him to skip around on his life's timeline. He's a time traveler!
A science fiction romance of sorts, this is one of my favorite novels. It explores aspects of love such as devotion and the possibility of soul mates. It is a beautiful novel told back and forth between Claire and Henry in the first person.
