This is the story of Joe—a reserved rocket engineer who leads a quiet, solitary life—and Fran—a brilliant astrobotanist working on the world’s first rocket powered by plant-based fuel. When Joe and Fran team up to prepare for the maiden launch of this revolutionary rocket, they immediately find themselves drawn to each other. However, romantic relationships aren’t exactly either of their strong suits. The situation gets complicated when three small, mischievous, and incredibly cute aliens find refuge in Joe’s home. Dunk, Velli, and Shirm are traveling between galaxies, fleeing from Zandro, a very determined but extremely clumsy space officer. Eventually, the little aliens realize that Fran’s rocket might be their chance to return home safely.
