The stories people tell are always about the things we left behind, and about the things we wish we could do again. The real story isn't about what you know; it's about what you wish you knew then. When my brother and my best friend fell in love - that was the end of everything I knew. Fraternal twins Nadio and Noelle share a close connection - and as Noelle's best friend since they were five, Keeley Shipley fit perfectly into their world. But everything changes after Keeley spends the summer before junior year at Oxford. When Keeley returns, Nadio falls in love with her. Noelle, ripped apart by resentment, sees her as an ungrateful rich girl. But Keeley has a painful story that she can't tell yet. As Nadio and Keeley hide their romance, Noelle dives into something of her own - a destructive affair with an older boy. Beautifully presented by dual narrators in a haunting stream of memories, this is the deeply moving story of how secrets can consume a friendship - and how love can heal it.
