Pleskit's new in school. He's also purple, bald and has a single stalk growing out of the top of his head! It's going to be an interesting first term . . .
Pleskit, Maktel, Tim and Linnsy are in deep danger: they have accidentally stowed away on an alien spaceship - a ship filled with the Fatherly One's worst enemies. Though they manage to avoid detection on the journey, when they escape, they realise they have left Earth far behind. Stranded on a planet full of enemies, the kids face their toughest challenge yet - how to find they way back home . . .
