Everything changes in a single moment for Dawn Edelstein. She's on a plane when the flight attendant makes an announcement: prepare for a crash landing. She braces herself as thoughts flash through her mind. The shocking thing is, the thoughts are not of her husband, but a man she last saw fifteen years ago: Wyatt Armstrong. Dawn, miraculously, survives the crash, but so do all the doubts that have suddenly been raised. She has led a good life. Back in Boston, there is her husband, Brian, her beloved daughter, and her work as a death doula, where she helps ease the transition between life and death for patients in hospice. But somewhere in Egypt is Wyatt Armstrong, who works as an archaeologist unearthing ancient burial sites, a job she once studied for, but was forced to abandon when life suddenly intervened. And now, when it seems that fate is offering her second chances, she is not as sure of the choice she once made.
