An unconventional love story between a man who has a genetic disorder that causes him to trip through time, and a woman who he first met as a young girl. The premise actually sounds pretty creepy, but it works in the book, and Henry doesn't come off as a skeeve. But their friend Gomez does.... The book is quite fast paced and told in non-chronological order, which hints at things to come and makes the book fairly un-put-down-able.
