Stoneheart

Deep in the City something had been woken, so old that people had been walking past it for centuries without giving it a second look.... When George breaks the dragon's head outside the Natural History Museum he awakes an ancient power. This prehistoric beast, sentry-still for centuries, hunts him down with a terrifying wrath. And this is just the beginning....

"Edie," said George, "we're going to do this together. I'll be right there with you. Anything, anyone trying to get you is going to have to come past me first." But when George makes his promise he is not aware that high on the rooftops an unseen gargoyle is watching them hungrily, quivering with anticipation for the moment when it will unfold its stone wings and pounce. The thing on the roof knows that nothing is over; nothing is finished.
