Out of Love begins at the end. Angel and Theo call it quits after nearly five years, and while holding a box of her ex-boyfriend's belongings, Angel wonders: How could they have spent so long together? When did they fall out of love? Were there good times before the bad? These are the questions we obsess over when a relationship ends, even when obsessing can do no good. But instead of moving forward through the emotional fallout of a break-up, Out of Love moves backward in time, weaving together an already unraveled tapestry, from tragic ending to magical first kiss. Each chapter jumps further into Angel and Theo's past, mining their history for the days and details that might help us understand love; how it happens and why it sometimes falls apart.
