He had a pair of burning torches. He ran them back and forth across his skin. He sipped from a bottle, breathed across a torch, and fire and fumes leapt from his lips.

He glared. He roared like an animal. That summer, life had seemed perfect for Bobby Burns.

But now it's autumn and the winds of change are blowing hard.

What can they do together on Bobby's beach? Is it possible to work miracles? Will they be able to transform the world?A stunning novel from the author of the modern children's classic Skellig - winner of the Carnegie Medal and the Whitbread Children's Book Award.
