In 1650s England, a young Puritan maiden is on a mission to save the baby of her newly widowed preacher—whether her assistance is wanted or not. Always ready to help those in need, Elizabeth ignores John's protests of her aid. She's even willing to risk her lone marriage prospect to help the little family.

Yet Elizabeth's new role as nanny takes a dangerous turn when John's boldness from the pulpit makes him a target of political and religious leaders. As the preacher's enemies become desperate to silence him, they draw Elizabeth into a deadly web of deception. Finding herself in more danger than she ever bargained for, she's more determined than ever to save the child—and man—she's come to love.
