This book was very confusing. It goes from 1991 to 1968 to 1988 so on and so forth. I couldn't make sense of it.The story is about Henry DeTamble. He has Chrono-Displacement Disorder. It causes his genetic clock to reset. "He finds himself misplaced in time, pulled to moments of emotional gravity from his life, past and future." He'll just disappear without warning.Then, there's Clare. She's met the future Henry in her past and he told her that they would be married.They meet again in 1991. Henry is 28 and Clare is 20. They fall in love.And then we go back and forth in time until nothing makes sense.Don't read this book. It's a waste of your time.
