Verity Baxter has lived - quietly, carefully - in Trinity Fields all her life. Then Ailsa and Tom Tilson move in next door and everything changes. Can Verity trust what she hears through the walls?

Either way, like the ivy that creeps through their shared garden fence, their lives are entwined now. And the knots can only get tighter.
