In this sequel to Airborn, Matt Cruse is on a training mission in a decrepit cargo airship when he comes across the ghost ship, Hyperion, an airship that hasn't been seen for 40 years and is rumoured to be full of treasure. Matt, his girlfriend Kate de Vries, and their sidekicks Hal and Nadina try to reach the Hyperion to claim the treasure. Their quest, however, does not go smoothly. Adversity in the form of air pirates, monsters and other dangers faces them at every turn. The setting of the story is a combination of the past and present - the characters wear Victorian dress, but have futuristic technology. .

English language arts grade 8 (2009). "The villains, John Rath and his boss George Barton, work for the Aruba Consortium that has a monopoly on production of airship fuel. This aspect of the story could lead to an interesting classroom discussion about oil cartels. As well, elements of Skybreaker echo the stories of Prometheus and Icarus, which provide other opportunities for expansion."--Ministry of Education website.
