This is one of my all-time favorite books. It's slow, it's heart-breakingly romantic, and it was perfectly timed for me. I read it my senior year of college, when I'd been with my boyfriend for nearly two years, and I was getting so tired of reading books about people falling in love. Me! I like most of the things I like because of the love stories involved, and I was getting tire of reading and watching and hearing about people falling in love. I wanted something about people STAYING in love, and man, this delivered.
The premise throws some people. Henry spontaneously time travels. He can't stop it, he can't do it intentionally. And his wife has loved him since she was six, though he first met her when she was in college. They have their problems--it's not easy, living every day, terrified that your husband is going to travel right right in front of a semi five years ago, you know? But it is romantic, and I love the characters.
