Trevor Benson never intended to move back to New Bern, North Carolina. But when a mortar blast outside the hospital where he worked as an orthopaedic surgeon sent him home from Afghanistan with devastating injuries, he comes to regroup in the dilapidated cabin inherited from his grandfather. Trevor isn't prepared to fall in love, yet from their very first encounter, Trevor feels a deep connection with deputy sheriff Natalie Masterson. Though she seems to reciprocate his feelings, Natalie remains frustratingly distant. Further complicating his stay is the presence of a sullen teenage girl, Callie. Claiming to be 17, she works at the local store and keeps to herself. Discovering that she was once befriended by his grandfather, Trevor hopes Callie can shed light on the mysterious circumstances of his grandfather's death, but she offers few clues - until a crisis triggers a race that will uncover the true nature of Callie's past.
