Down a deserted hospital corridor, nurse Abby Miller witnesses a patient's shocking murder. When the masked killer spots her, she's overpowered—and left for dead. Handsome doctor Blake Jamison vows to keep her safe while investigating the mysterious patient's death. But when he and Abby uncover a connection between the murder and the long-held secret of his adoption and possible Amish birth, the killer begins targeting them both. Amish-born Abby slowly learns to trust Blake with her life. But it may be too late to protect her heart from the high-society doctor who is sure to leave her behind.
