In a moment of desolation on a windswept beach, Garrett bottles his words of undying love for a lost woman, and throws them to the sea.

My dearest Catherine, I miss you my darling, as I always do, but today is particularly hard because the ocean has been singing to me, and the song is that of our life together . . .

But the bottle is picked up by Theresa, a mother with a shattered past, who feels unaccountably drawn to this lonely man. Who are this couple? What is their story? Beginning a search that will take her to a sunlit coastal town and an unexpected confrontation, it is a tale that resonates with everlasting love and the enduring promise of redemption.
