Zarf is a troll. That means, at this middle school of his, he is the bottom of the bottom on the social ladder. Even his friends Kevin (of Littlepig fame) and Chester (the Jester) are higher up the social ladder than he is. But then, what do you expect when you're the kid and grandkid of the trolls who bugged the billy goats?
Zarf's okay with his social nothingness. That is, until King Cheznott goes missing, presumably dead, killed (or kidnapped) by huge Snuffweasels. And his bully son (at least bully to Zarf), Roquefort, takes over. And throws Zarf in the dungeon. Where he (somewhat inadvertently) finds himself on a rescue mission. And, of course, hilarity ensues. Actually, the plot is really secondary in this book. It's mostly just about silliness.
This slim book is liberally scattered with pictures, making it perfect for the reluctant reader. And it's hilarious, which makes the appeal that much greater. At any rate, I laughed quite a bit and read it all in one sitting. Perfect, silly, stupid fun.
