In the Southern town of Lafayette Falls, a new life brings together a woman with everything to lose and a doctor with everything to prove. When a sickly infant is surrendered at the Lafayette Falls Medical Center, and orphaned soon after, pediatrician Aaron Kendall arranges to adopt him. After a painful divorce, the busy baby doc is about to realize his own dream of becoming a father when the baby's beautiful estranged aunt turns up. She doesn't exactly approve of the Kendall bachelor pad, complete with Aaron's cranky dad and wacky brother, forcing Aaron to form a risky alliance with her. Country singer-songwriter Lia Montgomery barely knew her half-sister, but she's determined her tiny nephew goes to a good home. If only she fit the bill herself, but her stressful life on the road is no place for a baby. Yet despite her misgivings, as she gets to know Aaron, she realizes the smart and sexy doctor is everything a child could want in a dad-and more unsettling, everything she's ever hoped for in a man. After all she's put him through, is it too late to form a family-and maybe put a song in the good doctor's heart?
