The second novel in an astonishingly imaginative fantasy trilogy that began with the critically acclaimed Advent

If there's one thing Gavin Stokes knows, it's that something unimaginably dangerous has returned to the world. A mad dog runs amok, a mermaid floats in the bay, and a wild beast stalks the countryside. He and others make the same strange claim: magic has returned. All signs point to it.

Now, Gavin's aunt has disappeared. A young girl who's been accused of murder vanishes from a locked cell. She is at large somewhere in a vast wilderness. Meanwhile, a desolate child leaves the home that has kept her safe all her life and strikes out into the unknown. And a mother, half mad with grief for her lost son, sets off to find him.

There is a place where all their journeys meet. But someone is watching the roads . . .
