With a Robot Army at My Back (Moon Hackers)

Who knew running a moon base would be so much work?

For thirteen-year-old Jo, it's not quite the fun and games she imagined, even with her best friend in charge. It's been forty-seven days since the rebels kicked Big Smile Corp out of the Lunar Coding Complex, and everything is going... not quite to plan. The eel tanks need cleaning, meals need cooking, and is it normal for the air handlers to break this often?

After a disaster strikes the base, putting everyone in danger, Jo must go on a journey across the moon in search of supplies from a neighboring base. But driving a rover for days is no easy task, especially when Big Smile Corp tries to sabotage you every step of the way. The oxygen tanks are running low, the food supplies are dwindling back at the base, and are the robots friendly or dangerous?

With a Robot Army at My Back is the sequel to How I Hacked the Moon, the bestselling sci-fi adventure for ages nine to adult.
