A new life. A new identity. And a haunting past. In April 1943 a young woman washes ashore on a deserted beach in Cornwall, England. With shorn hair and a number stitched on her tattered chemise, Alice is the survivor of a ship torpedoed by a German U-boat. She’s found by the mysterious Viscount Jack Trewella, who suspects that she’s a prisoner of war or a spy. But the secret Alice asks Jack to keep is one he could never have guessed and it creates an intimate bond he never expected. With her true identity hidden beneath the waves, Alice grasps the chance to reinvent herself. But as she begins to fall for Jack, she discovers he has secrets too – ones echoing the legend of a mermaid said to lure men into the dark depths of the sea. For two strangers in the shadow of war, lost love and haunting memories, is it time to let go of the past? Or to finally face it – whatever the risks?
