London 2014—Catherine Howard stumbles upon the tomb of her granddaughter, Anne Howard Brandon, who'd been swept back through time. Horrorstruck, she discovers Anne was murdered in the year 1562.

Elizabethan England 1562—Dr. Jonathan Brandon, Anne's husband, pens a desperate message to Catherine, which gives the details of his wife's kidnapping and murder, and the plea to "find a way to undo this!"

Upon discovering the ancient letter, Catherine calls upon a time-traveling priest, Father Daniel, to rescue her precious granddaughter. But journeying back to the sixteenth century is a dangerous undertaking, the life and death risks sobering and real. Will Daniel survive? Can anyone thwart the evil that threatens Anne, or is the timeline immutable, her fate sealed? Daniel calls upon the forces of heaven and earth—including a secret Vatican society of time travelers—to aid in this quest. Will they be able to help? Can they change the course of history? Will time rewind?
