S – The Horn Book (starred review)

After the excitement of his encounters with pirates, cloud cats, and the rich and alluring Kate de Vries, Matt Cruse finds life at the Airship Academy significantly anticlimactic. When, on a training mission, he glimpses the legendary Hyperion, the ghost airship that is the relic of a crazed jillionaire's last hurrah, he sees a fast-track to the wealth he needs to woo Kate properly. Enter shady thugs, a mysterious gypsy girl, and the dashing captain of the fabulous skybreaker Sagarmatha, an airship especially designed to attain the extreme altitudes where the Hyperion drifts, ripe for salvage. Whereas Airborn was almost entirely (and exhilaratingly) plot-driven, this sequel manages to delve into its characters even as it delivers yet another breakneck flight through the skies of its beguiling alternative world. The romantic tensions among the four adventurers headed for the Hyperion allow plenty of opportunity to explore their personalities as they steer the Saga toward the ghost ship. Killing altitudes, conflicting agendas, and the ruthlessness of the Aruba Consortium goons who are also intent on capturing
the wealth and secrets of the Hyperion provide more than enough material for heart-stopping action scenes that will please even the most jaded of readers.
