Lily Childs had made her peace with dying. If her leukemia didn’t kill her, then serial killer Danny Jordan certainly would. But then Aidan Knight crashes through her balcony door and saves her life. Finding herself hopelessly attracted to the handsome and mysterious billionaire, and desperate to remain in his life, she accepts his offer to be her guardian.
Time-travelling vigilante Aidan Knight had made a life out of saving damsels in distress, and then walking away without looking back. But after saving Lily, he couldn’t stay away. Like a moth to a flame, he kept returning to her. But would she still want him if she found out the truth about him and his deadly talents?
