Last Summer in Outer Space (Hardcover) (ISBN-13: 9781728486192)

Jack's eighth-grade year aboard the PSS 118 is coming to an end. And the students and faculty of the best public schoolship in the galaxy (if it does say so itself) are on the verge of completing their mission. If all goes well, they'll soon foil the sinister alien plot that's put all of humanity in danger.

But this is still middle school. So all does not go well.

When the original plan backfires, it's up to Jack, Ari, and Becka to take on the evil Minister one more time and make the galaxy safer for everyone.
