To save her son, she'll marry a man who has sworn off love. After her wealthy in-laws launch a vicious custody battle, widowed nurse Kelsey York is out of options. Her only hope is a marriage of convenience with Preston "Mac" MacCormack-the island's resident grumpy billionaire who is determined to sail away from his own tragic past. The deal is simple: she gets a husband with the power to protect her son, and he fulfills his grandfather's dying wish. But due to their forced proximity in a small cottage on the coast of Maine, their carefully constructed arrangement begins to crumble. The lines blur between protector and partner, between a fake marriage and a real found family. Mac finds himself captivated by the fierce single mom and her bright, curious son, the two people who threaten his vow of solitude. Just as they begin to imagine a future together, a shocking act of violence reveals the true depths of their enemy's obsession. And when a grim discovery is unearthed on the grounds of the island's historic mansion, they realize the secrets of Widow's Point are far deadlier than they ever imagined. This page-turning romantic suspense is perfect for readers who love a protector hero, a resilient heroine, and a story where a temporary arrangement leads to a love that could last forever.
