Leaving behind a career filled with danger and secrets, Piper Luck arrives in Duck, North Carolina, on her fortieth birthday, determined to build a new life. Starting with The Roots Beneath Us, a local course her friend and father figure swore would transform her, she embarks on a new journey. However, on the first day of class, only one other person shows up-a shy, guarded man.

Like Piper, Boone Winters just moved to the Outer Banks at the suggestion of his now deceased mentor and boss, who promised Boone a job when he arrived if he worked up the courage to leave an abusive relationship. The job: Build a luxurious oceanfront home. However, there are contingencies. He must attend The Roots Beneath Us program, have an accountability partner, and live alone.

With no other course participants, Piper becomes Boone's accountability partner. Together, they work through the course by facing their fears, setting goals, overcoming obstacles . . . and forging an unlikely friendship that evolves into something deeper. Nonetheless, when their previous lives resurface and threaten the tentative roots they've planted, they must each courageously confront their past demons once and for all in order to claim their future.
