On the day of a late spring storm, in Chicago, Autumn Manning boarded an “L” train. A bomb explodes, killing everyone in the train car except for Autumn—the sole survivor. A year has passed and Autumn suffocates under a blanket of what ifs and the pressing desire to bring the victims back to life, every day, if only for her. She doesn’t want their stories to be forgotten. She wants to undo what cannot be undone. An unexpected ally joins her efforts, also seeking answers and trying to find a way to stumble ahead. But one victim’s husband, Paul Elliott, prays to let the dead—and their secrets—rest in peace, undisturbed and unable to hurt his loved ones. Caught between loss and hope, these restless souls must release the past to embrace a sovereign God.
