"As she [Spensa Nightshade] is stuck in the Nowhere, Spensas companions FM and Jorgen in Skyward Flight are left on Detritus with a new mandate: figure out how to use the hyperdrives so that humanity can escape the planet and find allies among other species oppressed by the Superiority. First comes a distress call from Minister Cuna and other diones on the abandoned outpost of Sunreach. Alaniks people on the planet ReDawn and the Kitsen from the planet Evershore also need Skyward Flights aid in their desperate battles."--Provided by publisher.
