How I Hacked the Moon

The instant Amazon bestseller that launched the series — a thrilling middle-grade sci-fi adventure for ages nine to adult.

Life at the Lunar Coding Complex is boring, not that thirteen-year-old Moon Girl cares. She finds comfort in its predictability—her first real friend and her love of AI coding keep her anxiety in check. When a harmless prank with her charismatic bestie attracts the attention of rebel hackers led by Moon Girl's crush Dovrin, she's thrilled to join their crew.

But as they uncover Big Smile Corp's dangerous secrets, Moon Girl faces impossible choices: her friendship, her crush, or everyone's safety. Even if they crack the system, do they want to escape back to Earth? And if they fail, what will the sinister corporation do to silence them?

With a Robot Army at My Back

The sequel to the bestselling middle-grade sci-fi adventure How I Hacked the Moon.

It's been 47 days since the rebels kicked out Big Smile Corp from the Lunar Coding Complex, and everything is going... not quite to plan. It turns out that running a moon base is a lot of work. The eel tanks need to get cleaned, meals must be cooked, and so many repairs made. For Jo, it's not quite the fun and games that she imagined, even with her best friend in charge.

After a disaster strikes the base, putting everyone in danger, Jo must go on a road trip across the moon in search of supplies from a neighboring base. But driving a rover across the moon for days is no easy task. What will she find at the other base? And can she make it back in time to save her friends?
