When the ill-fated maiden voyage of the Titanic leaves thirteen-year-old Olivia Davenport orphaned she's sent to live with her guardians the Fairchilds in their huge Jacobean mansion - Merriford Manor.

That is until she hears a voice from behind the wall in her tower bedroom. A voice from a man called Seth. At first she thinks he's a ghost. But it soon becomes clear that he lives in an overlapping world that is just a shudder in time away from her own. A world where the Titanic never sank. . . And everything since has been just slightly. . . different. All Olivia wants is to find a way into his reality. And not just to see the faces of her beloved parents once again. But also to meet Seth. Who might just be the love of her life. . .
