Edge Chronicles 1: The Curse of the Gloamglozer Award-winning team by Paul Stewart (author) and Chris Riddell (illustrator) (UK edition)

Fourteen-year-old Quint Verginix is the only remaining son of famous sky-pirate Wind Jackal. He and his father have journeyed to the city of Sanctaphrax – a great floating rock, bound to the ground below by a chain, its inhabitants living with their heads literally in the clouds.

But the city hides a dangerous secret: deep inside the great rock, something horrible lurks. With his father away, Quint may be the only one who can save Sanctaphrax from the dreaded curse of the gloamglozer . . .

The Curse of the Gloamglozer is the first book of the Quint Saga – first trilogy in The Edge Chronicles, the internationally best-selling fantasy series, which has featured on the UK and the New York Times best-seller lists and sold more than 3 million copies. There are now 13 titles and four trilogies in the series, but each book is a stand-alone adventure, so you can read The Edge Chronicles in any order you choose.
