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. After five successful missions - each of which has tested their wits, courage and team spirit - the Taranauts head for the blazing hot world of Shimr in search of the golden Citrines. Meanwhile, determined to stop them, a brand new army of Mithya's Most Ruthless, goes into full combat mode. Will all three Taranauts make it safely through the Bhoolabyrinth? Can Tufan survive the oxdrogen-deprived darkness of the underground city of Oop R' Ville? What is the secret of the Drip-Trip Cave? And how in Kay Laas will they tackle the most unexpected problem of them all - Mithyakos who don't want their stars rescued? Will the Citrines return to Tara? Read and find out!
