A Space Academy student and his time-travelling robot stop an evil villain from taking over the Solar System in this children’s sci-fi classic.

Fourteen-year-old Jeff Wells, a cadet at the Space Academy on Mars, is in danger of being kicked out unless he can improve his grades. With a little help from the academy’s commandant, Jeff finds a robot named Norby to help him study. But Norby’s no ordinary robot. He has the only mini-anti-gravity device in existence.

Norby’s special abilities suddenly come in handy when a villain named Ing targets Jeff’s older brother in his quest to conquer the Solar System. When Ing takes over Manhattan Island, renaming it “the Kingdom of Ing,” Norby and Jeff put studying aside to teach Ing a lesson!

“With elements of adventure, exploration, other worlds, and fantastical science, Nemesis and the Vault of Lost Time is an exciting middle-grade novel with plenty of suspense… Behind the adventure are important messages about believing in oneself and finding inner strength.” — The Children’s Book Review

Thirteen-year-old Max is a daydreamer. It gets him into trouble at school, but his restless curiosity really turns problematic when he runs into a mysterious professor at his uncle’s bookstore. The old man informs Max that time is being sucked out of the planet by invisible bandits, stolen from unsuspecting people one breath and one sneeze at a time, and is being stored in a central vault. Once full, the vault will fuel a hungry horde of invaders looking to cross into earth, and cross out all its people. What’s more, the professor claims he knew Max’s missing scientist father. With the help of his best friends, Derek and Samantha, Max must harness his compulsive curiosity and find passage to this place called Nemesis to stop the sticky-fingered time thieves and halt their planned invasion. But when the professor goes missing and the clock starts ticking, Max discovers far more than he imagined. Just how much Max is willing to sacrifice hinges on the realization of just who or what he is beyond the bounds of time.
