Publisher's Summary
Danger lurks aboard the Kuari Princess as Rebel heroes try to uncover the purpose behind a top-secret Imperial rendezvous while fighting notorious pirates -- the Riders of the Maelstrom.

A mission to rendezvous with a top Rebel spy on Aris goes wrong. The Rebels are chased by better than a full company of stormtroopers, strafed by Imperial sky swoopers, and risk death to escape along hundred-meter high tree limbs. When they manage to smuggle themselves onto the luxury liner Kuari Princess, the Rebels know they can finally rest easy. The Rebels are wrong.

Which Imperial officials are having a secret meeting aboard the Kuari Princess, and why? Can the Rebels stop the Imperial plot? Can the Rebels prevent the Riders' awful plan of destruction? Outmanned, outgunned and out of time, the Rebels must forge a victory from only their courage and resourcefulness.
