Ansel's new master slays dragons for a living. He says he's hunted the monstrous worms all over Christendom-and he has the scars to prove it! But is Brock just a clever trickster in shining armor? Ansel is sure there are no such things as dragons. So what is the man-eating creature that lives in the crags of Dragon Mountain? As he and Brock climb the perilous ice-face to its lair, Ansel is about to discover the horrifying truth. A heart-pounding new fantasy with a brilliant twist from Philip Reeve, one of the world's greatest writers.
