They say the Hollow Sea is cursed. A wild expanse separating the remote islands of St Hía, not even the locals brave its treacherous waters.

But new arrival Scottie feels a pull she can't ignore. Because behind the curse is the legend of Thordis: a woman whose story feels eerily familiar. No one knows what became of her, but Scottie believes Thordis's fate may answer questions about her own past.

Despite the islanders' warnings, Scottie sets out to discover the truth. But as she dares to cross the Hollow Sea, will its secrets give her the answers she needs?

Or will the past drag her under?
