Noah Zarc: Mammoth Trouble

By D. Robert Pease

Noah lives for piloting spaceships through time, dodging killer robots and saving Earth's animals from extinction. Life couldn't be better. However, the twelve-year-old time traveler soon learns it could be a whole lot worse. His mom is abducted and taken to thirty-first century Mars; his dad becomes stranded in the Ice Age; and Noah is attacked at every turn by a foe bent on destroying a newly habitable, post-apocalyptic Earth.

Traveling through time in the family's immense spaceship, Noah, a paraplegic from birth, must somehow care for the thousands of animals on board, while finding a way to rescue his parents. Along the way, he discovers his mother and father aren't who he thought they were, and there is strength inside him he didn't know he had.
