Pushed high into the sky by a storm over the Indian Ocean, the decrepit training ship Flotsam makes an astonishing discovery before being forced to descend. Adrift at 20,000 feet is a tattered, ice-crusted airship bearing the name Hyperion. Could it really be the legendary lost craft, now a vast treasure, a frozen mausoleum to a ghostly crew? Matt Cruse is the only member of Flotsams oxygen-starved crew able to remember the ghost ships coordinatesand it seems as if everyone in the fabulous city of Paris wants them. Matt and Kate de Vries are challenged with another thrilling adventure, this time among the icy dangers and strange wonders of the upper atmosphere. Hang on for the ride of your life as Kenneth Oppel, one of Canadas greatest childrens authors, returns to a richly imagined world of airships and adventure!
