Stoneheart — Charlie Fletcher

A city has many lives and layers. London has more than most. But not all the layers are underground, and not all the lives belong to the living. Twelveyear-old George Chapman is about to find this out the hard way.

When, on an otherwise normal day, George breaks the head from a stone dragon outside the Natural History Museum in a tiny act of rebellion, he inadvertently awakens an ancient power. The results are instant and terrifying: a stone pterodactyl unpeels from the wall and starts chasing George. He runs for his life, but the strangest part is, no one around him can see what he's running from. No one except Edie, who is also trapped in this strange world.

Now that George has disturbed the fragile truce between the warring statues of London, he is forced into a race for survival, where nothing is what it seems, and its never clear who to trust.

And this is just the beginning...
