When a planet-destroying Delver suddenly appears in the sky of Detritus and vanishes just as suddenly, FM knows that the last free human society got lucky. Her Skyward Flight companion, Spensa, figured out how to draw this Delver away, but it won’t be so easy next time.|
The forces of the Galactic Superiority will be back—and if the Defiant Defense Force can’t figure out a way to escape the planet, humanity’s destruction is only a matter of time. Spensa’s mission to infiltrate the Superiority unveiled the secret to their hyperdrives—a cytonic slug species called the Taynix. Now FM’s flightleader, Jorgen, has found a large group of Taynix hiding in the caverns far below Detritus’s surface.
