Zoomway Time of the Swarm

Publisher's blurb: The Zoomway travellers arrive on the planet Nessos-Perijene, an overlooked part of the Tri-Silver Federation star empire. After helping the local settlers against a plague of giant Isopods, the heroes meet "Jane Smith" a fellow alien -and a fellow Zoomway traveller! But barely have introductions been made and stories swapped when an invasion begins by the dimension-hopping OCTRONS!
