When novice nun Joanna Stafford learns her cousin is about to be burned at the stake for rebelling against Henry VIII, she breaks the sacred rule of enclosure and runs away from Dartford Priory. But when she and her father are arrested and sent to the Tower of London, she finds herself a pawn in a deadly power struggle. Those closest to the throne are locked in a fierce fight against those desperate to save England’s monasteries. Charged with a mission to find a hidden relic believed to possess a mystical power that has slain three Englishmen of royal blood in the last three hundred years, Joanna and a troubled young friar, Brother Edmund, must seek answers across England. Once she learns the true secret of her quest, Joanna must finally determine who to trust—and how far she’s willing to go to protect her life, her family, and everything she holds dear.
