Maverick

"Please protect my baby boy."Confirmed bachelor Lucas Nash traded the Rocky Mountains for San Francisco Bay nine months ago and vowed never to return. Then he discovers a newborn in his boat, with a note from his ex pleading he protect her baby. Suddenly forced to learn how to care for an infant, Lucas finds an unlikely ally in private eye Samantha Dorsay. Sparks and bullets fly as they confront the Wyoming town that rejected him to search for the baby's mother, fighting to keep the child--and each other--alive long enough to find the truth.
