When Keely O'Toole returns home to Village Green, Colorado, she lands in a very unfamiliar role—as guardian to her cousin's seven-year-old daughter. Keely loves little Felicity, but she's in over her head. And the only person she can turn to for help is former army ranger Dr. Ethan Scott. Her best friend's brother, a man she can hardly speak to without bickering. But when Keely and Ethan bond while taking care of Felicity, everything changes. Keely wants to give Felicity the best Christmas ever, and Ethan is just the person to light up their holidays…and their lives.
