Mistreated for being mixed-race and forced into hard labour at a workhouse in West Hoboken, New Jersey, young Max and Molly are ordinary orphans - or so they think. That is, until a wise old man hears their last name: M'Chawi. Rattled by this realization, he sends them off on a journey that will uncover the secret behind their mystic lineage and give them purpose and power far from home - on the Moon! There, they encounter the Moon's fantastic inhabitants: the Sky Pirates and their merciless Queen Melissa; the Groos, blue primates and genius mechanics - literal grease monkeys - and their robot protector, Moma Machina; and a kingdom of singing spiders giant enough to eat a man. Looks can be deceiving, and those who first appear frightening can turn out to be allies, and even friends. Take Prince Grakko, pampered heir-apparent to the Bat-People. The Moon is a land locked in constant battle. Races live in fear and ignorance of one another. To make matters worse, the siblings' getaway isn't as clean as they'd hoped, and the Earth Queen's Grand Inquisitor is hot on their trail. Armed with a bejewelled dagger, pendant, and pure hearts, Max and Molly must unite the denizens of the Moon under a common cause, before humanity's folly reduces their world to rubble. Equal parts Jules Verne and Bone, The Moon Prince is a star-spanning, page-turning epic for the ages.
