2019: Lucy awakens from a dream to find her hands around her ex-lover’s throat. Horrified, she flees to her older sister’s house on the Australian coast, hoping she can help explain the strangely vivid nightmare that preceded the attack―but Jess is nowhere to be found.
As Lucy awaits her return, the rumors surrounding Jess’s strange small town start to emerge. Numerous men have gone missing at sea, spread over decades. A tiny baby was found hidden in a cave. And sailors tell of hearing women’s voices on the waves. Desperate for answers, Lucy finds and begins to read her sister’s adolescent diary.
