The Hal Junior series is written in a similar style to the adult Hal Spacejock books, except the Hal Junior titles are shorter and feature a younger protagonist. In other words, most adults will enjoy these books too! (Reading levels detailed below)

'I've heard of food going off, but this is ridiculous!'

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!



Hal Junior: The Secret Signal was released in September 2011 to stellar reviews. And, of course, everyone started asking about book two.

Well, the good news is that I've already finished the next book. The title is Hal Junior 2: The Missing Case, and it features campfire practice, a VIP and a new friend for Hal Junior ... someone who can outdo him in almost everything!
