July 1969. Clive, Iowa, Earth. Sixteen-year-old Allie has a big decision to make: Watch the lunar landing with her mom in their run-down double-wide trailer or boost to the stars aboard a grumpy, sentient deep space exploration vehicle (DSEV-424) buried in her backyard for 5,000 years.

Accompanied by Gem, a dead space captain, now a glitchy hologram, Allie stops on the moon and surprises Neil Armstrong and Buzz Aldrin aboard the Eagle lunar lander. (Neil never mentioned the encounter to Houston).

With Gem as her guide, Allie survives her first space battle and drops Gem off at a military regrow center in the middle of a spaceport casino. The teen's adventure lifts off at a military space academy, where she faces danger, makes friends, battles enemies, and discovers her own surprising abilities.

Along with Rin, Sky, and Gem, Allie sets out on a mission to locate and defeat a rogue fleet led by Naomi, a mad-as-a-hatter warship, all while navigating the complexities of growing up and finding her place in the galaxy.
