The #1 New York Times bestselling author of A Spark of Light returns with a thought-provoking and otherworldly novel about the fates that we choose for ourselves and what happens when we have the chance to choose again.

Dawn Edelstein knows everything there is to know about dying. She specialises in helping her clients make peace with the end of their lives. But as she's flying home from her latest case, she is forced to confront her own mortality for the first time.

Instead of seeing her brilliant quantum physicist husband and their beloved daughter flash before her eyes in what she assumes are her last moments, only one face is shockingly clear: Wyatt Armstrong.

Safely on the ground, Dawn now faces a desperate decision. Should she return to Boston, her family and the life she knows, or journey back to an Egyptian archaeological site she left over a decade earlier, reconnect with Wyatt, and finally finish her abandoned magnum opus, The Book of Two Ways?

As the story unfolds, Dawn must confront the questions she's never truly answered: What does a life well-lived look like? When we depart this earth, what do we leave behind of ourselves? And who would you be if you hadn't turned out to be the person you are right now?
