Everything is up in the air when the problem-solving best friends Sanity and Tallulah find themselves co-pilots on an unplanned adventure filled with action, adventure, and dangerous situations. ​ Tallulah is great at piloting! And with her learner's permit freshly reinstated, she has the perfect opportunity to prove it: filling in on the mail route to nearby stations while all the regular pilots are out sick. It's her first big solo flight, and yeah, okay, her parking could use some work, but she's not even a little bit nervous—she's got Sanity along as copilot, plenty of old flight logs for navigation, and they'll be in radio contact with Wilnick almost the whole time. All they have to do is follow the pre-approved route and stay out of the dangerous, uncharted, explosives-littered debris cloud . . . no matter how tempting a shortcut it is. Oh, and don't cross the military blockade into the United Territories, obviously. See? No sweat! Sanity and Tallulah's pre-approved route didn't say anything about space stations exploding, enemies in need of rescue, or getting caught in the middle of a border crisis in danger of escalating into all-out war, but sometimes totally awesome pilots have to change plans on the fly, and only an excellent copilot can keep things from going completely upside down.
