Four women, four stories, and a chance encounter that changes everything.

Still reeling from a recent breakup, Demi, a Greek-American banquet manager, joins her mother, aunt, and cousin on a trip to Greece, hoping to clear her head, heal her heart, and take a break from an unfulfilling job. Her plans for a relaxing holiday are derailed when their rental car breaks down on their way to the coast; that is, until they are rescued by a villager and her charming grandson, Stavros. While Demi navigates this unexpected romance, her mother, aunt, and cousin examine their own fears, hopes, and dreams, aided by Charles, a witty British author who endears himself to them with his good humor and sage advice. Demi's whirlwind romance ends abruptly when she returns to the States despite Stavros's pleas for her to stay with him. Upon her return, she must confront her feelings for Stavros and her impossible job situation. With Charles's advice in mind, the ladies tackle their issues.

Demi gets a job opportunity that would take her away from Pittsburgh, and she must decide whether to leave her family for a fresh start or stay where she has always been comfortable. The situation becomes more complicated when rekindling the romance with Stavros becomes possible. When fate intervenes, along with Demi's ex, her path becomes even more tangled.

Set in a charming Greek village, When the Only Light of the Moon follows two sisters and their daughters as they navigate individual journeys of self-discovery through the unexpected help of strangers. The crystal blue Mediterranean skies and silvery olive groves provide a magical backdrop for this lively story of romance, realization, and renewal.
