This is an Apple Books audiobook narrated by a digital voice based on a human narrator.

Space Station Oberon is expecting an important visitor, and everyone is on their best behaviour. Even Hal Junior is doing his best to stay out of trouble!

From multi-coloured smoke bombs to exploding space rations, Hal Junior proves ... trouble is what he's best at!

(The Hal Junior series is set in the same universe as Hal Spacejock, and there are cameos by several characters. Hal Junior's mum, Harriet Walsh, features heavily in Hal Spacejock 4: No Free Lunch.)

Middle-grade science fiction.
