Rachel Olmsted leaves her worries behind and boards the Grand Islander for a journey north along the beautiful New England Coast. Her only plan is to enjoy herself. That is until she encounters the handsome man in the cabin next door. Even though Dalton Swain is one of the owners of the luxurious ship, his itinerary for this cruise is pure relaxation. An instant attraction between Rachel and Dalton leads to a night in her cabin and an agreement to embark on a shipboard romance with no strings attached and no future beyond the eleven-day cruise. As the weather cools and the autumn leaves turn, the couple explores seaside villages and their temporary relationship. Soon both Rachel and Dalton realize the joy they feel could become love. Are they willing to negotiate a new agreement that will last long past the change in season? As the head physician for Coastal Cruise Lines, Dr. Camille Swain cares for the passengers and crew of the Grand Islander. Caring for others keeps her busy and fulfills her professional dreams, but she could use some TLC of her own when it comes to her heart. Devastated by a broken engagement, she’s not ready to trust her heart to anyone. However, when a childhood crush and lifelong family friend boards the Grand Islander, Camille finds it hard to resist him. Grayson Morris is the best man for his brother who is getting married on the Grand Islander. The Morris family has been cruising with Coastal Cruise Lines for decades, and Grayson suggests they all go along for a combined vacation and wedding on the decks of the elegant ship. Reconnecting with his childhood and teenage crush Camille Swain is part of his motivation for planning the family cruise, and being with Camille takes him back to carefree days. Is their relationship built on an idyllic childhood of summer nights on cruise ships, or could Camille and Grayson have a present and a future?
