Thirteen-year-old Stanley Brambles has returned to his normal, boring life in the sleepy town of East Stodgerton. School will be starting again soon, and his incredible adventure on the high seas of Terra already feels like a distant memory. Stanley has all the problems of a normal kid his age-homework, bullies, vindictive teachers, unrequited crushes-but he is also troubled by dreams: horrible nightmares, and visions of a mysterious giant blue crystal floating high above a distant jungle... The crystal is very important-of this, Stanley is certain, but what is it, really? Where is it? How is he supposed to find it? As fate would have it, Stanley and his friends are once again suddenly and unexpectedly uprooted from their normal, boring lives, and cast back into the wilds of Terra. This time, their adventures will take them into the dark and dangerous jungles of Verduria, the Green Continent, in search of the Lost City of Quetzal'Khan, the rumoured home of a certain giant floating crystal, and of an evil power that is slowly corrupting the jungle.
