Eternal Sea — Alice Alfonsi

According to Egyptian legend, if two lovers place locks of their hair in a cat-shaped urn at midnight on the eve of the new year, their souls will be bound together for eternity....

On her deathbed, Jenny Smithton's last request is for her fiance, Eric Wolfe, to carry out this ancient ritual. But when Eric himself dies in a bitter fight over the very same urn, his soul is taken by the sea. Having lost Jenny forever, he can only visit his former home and watch helplessly as it falls apart over the decades. Then, after more than a century goes by, a woman appears. For reasons unknown, he is immediately and irresistibly drawn to her -- as she is to his old seaside home. Her name is Miranda Burke -- and she is the only one who holds the key to unlock his soul from its watery grave....
