Caves of Challenge. Guardians of Glede: Next Generation, #1

Return to the land of Glede for new adventures with the next generation!Their heads filled with stories of adventures spun by their father and uncles, Princes Vantann and Thomlin Merripen decide to have an adventure of their own. Through an old book, they learn of the Caves of Challenge. If they can survive the challenges within the caves, they will emerge as men. Blackmailed by their young friend, Shuri, the boys agree to take her along.
Before the trio has a chance to adequately prepare, however, they are sent to the Caves by haphazard magic. Once there, Shuri and Vantann are captured by War Gnomes, while Thomlin is lost in a dark swamp. His only consolation is that, somehow, he has snagged King Jansson van Tannen on the magic strand. Jansson is reassuring, telling Thomlin that there will be a rescue party sent out and all they need do is wait.
But the rescue party is having trouble of their own, and they find much more than they bargained for in the Caves. The question now becomes, who will be forced to stay in the Caves of Challenge forever.
