Mithya's eight worlds - Shyn Lustr Sparkl Glo Dazl Shimr Syntilla and Glytr – were plunged into darkness when the wicked Shaap Azur captured all its 32 stars. There was no hope until Zarpa Tufan and Zvala - three bright and brave Taranauts with special gifts - set out to bring back light and cheer to Mithya.

With three successful rescues under their belts the Taranauts head west determined to notch up another win against their foes. But things take a nasty turn right at the start - the Marani of Glo is taken hostage! What’s worse Ograzur Dusht now has a secret agent in the Taranauts’ camp a spy who is known only by the code name Dro Hie.

Can the Taranauts get safely across the fearsome Budbudana and the treacherous cliff paths of Pur Butte? Will they survive the motion-sensitive lightning hurlers of Wilderwolf Gorge? Does the pink-crested warbler break up Zarpa and Zvala's friendship forever? And who is the traitor Dro Hie? Will Glo get its Rubies back?
