In the great floating city of Sanctaphrax, blizzards howl through the streets as the Edgeworld descends into an endless winter. Quint, the son of a sky pirate, has just begun his training at the Knights Academy—training that involves heading out over the Edge on tethers to develop his flying skills. But when Quint breaks the rules and sets off for Open Sky on his own, he runs into the great sky leviathans known as cloud-eaters and must use all his skill and ingenuity if catastrophe is not to strike the Edgeworld. . . .
The collection also includes a beautiful fold-out timeline of the Edgeworld and CLOUD WOLF and THE STONE PILOT, World Book Day stories that fans have repeatedly asked to see again.
