Yoko is off on an intergalactic journey this time! One night, on an isolated moor, Yoko, Vic and Pol are eagerly waiting for their friend Khany. When she arrives, she whisks them away on a shuttle and takes them not to one of the Vineans' underground facilities, but to a station near Saturn. And that's only the first leg of their journey! They're soon invited to travel much, much further: the Vineans have decided to return to their planet, to see if it survived the cataclysm that drove them into exile.
