Amazon.com description: Product Description: Following The 13½ Lives of Captain Bluebear and Rumo & His Miraculous Adventures comes a third hilarious and beloved 'Zamonia' book, the most popular yet. It is a fantastic tale for every book lover.

Optimus Yarnspinner inherits from his godfather an unpublished manuscript by an unknown writer and sets off to track down the mysterious author, who disappeared into Bookholm -- the so-called City of Dreaming Books. Yarnspinner falls under the spell of this book-obsessed metropolis, where an avid reader and budding author can find any number of charming attractions: priceless signed first editions, salivating literary agents, and for-hire critics. But as Yarnspinner pursues the trail of the missing author, the darker side of Bookholm begins to unveil itself -- cold-blooded book hunters, fearsome cyclopean Booklings, sharp-toothed Animatomes, and of course, the Shadow King, whose howls rise from deep beneath the city at night. Will Yarnspinner survive his quest into this world where reading is a genuine adventure?
