Marcus doesn't celebrate Christmas anymore. Not since the holiday massacre of his entire family left him an orphaned child, traumatized and alone.

Taken in by a reclusive billionaire with a secret identity, Marcus was trained to take the older man's place when he could no longer serve as the elusive crime-fighter known as the Guardian.

Casey is a reporter, but unlike every other member of the press, she's not after the Guardian to unmask him. She needs his help to protect her younger sister. Someone from her shadowy past is after her, and Casey is sure she's in danger.

Marcus couldn't have known that helping Casey would bring him into the midst of the huge loving family he never knew he had, much less into Casey's loving arms. Or that helping Casey would unwrap a Christmas miracle that would heal his wounded heart.
