Plot
In 2063, space travel has become possible and commercially viable; a group of students from Caird High School departs to the nearby planet of McPa for their Planetary Camp. Soon after the group arrives on the planet, the nine children encounter a mysterious and unforeseen intelligent sphere of light; it attacks them, transporting them into the distant depths of space. Floating in orbit around an unknown planet, they discover an old abandoned spacecraft nearby. Finding it in working order, they resolve to use the ship to return home. To do so, they must cross the 5,012-light-year gulf of space separating them from home by visiting alien planets, the names of which are all anagrams, harboring life to replenish and manage their limited resources.

The long and dangerous journey home aboard their vessel, which they name Astra, brings with it new character revelations, strengthening the bonds they share, and the eventual realization that the stakes of their journey are far higher than any of them could ever have realized.
