In a trio of novellas, supporting characters take center stage to battle treachery and cement alliances with aliens while the series' protagonist is off on a quest. Separately published in 2021 as e-books, the three tales included here string together both personal and political developments: Sunreach sees empathetic fighter pilot FM and engineer Rig, both White, awkwardly reach the smooching stage while learning how to work with adorable talking slugs that have cytonic powers. Violet-skinned Alanik has to overcome mistrust of humans to enlist their aid in fending off an attempt by supporters of the oppressive galactic Superiority to take over her planetary government on gas giant ReDawn in the eponymous second story. Finally, in Evershore, Skyward Flight leader Jorgen, who reads as Black, discovers both command potential and superpowers of his own while coordinating a defense of the valiant (if furry and squirrel-sized) kitsen. All three episodes kick up the action with both large- and small-scale battles in air and space--all brisk if remarkably low in explicit fatalities--dovetailing neatly in the end into the closing events of Cytonic (2021). Sanderson credits Patterson with the lion's share of the writing but adds five deleted scenes from his series opener, Skyward (2018), with commentary as a literary lagniappe. Each novella opens with skillful character portraits in contrasting styles by the two illustrators. Hot pilots slug it out with the galactic overlords in a collection that will please series fans.
