On the Isle of Sampetra, Emperor Ubla, better known as Mad Eyes, sends his lizard army on a mission to capture Redwall. Meanwhile the inhabitants of Redwall are on a mission of their own--to solve the six fiendishly difficult riddles that will lead them to the rose-colored gems, the Pearls of Lutra. As they get closer to solving to riddles, the lizards get closer to Redwall and a battle to the death begins.
One of the excellent fantasy adventure series about the mystical Redwall, Pearls of Lutra is a magical, mind-blowing adventure that never disappoints. Brian Jacques expertly weaves his web of intrigue through the pages, capturing the imagination with a stroke of a pen as if he were a wizard with a wand. Challenging, colorful, and, most importantly, readable to the point of addiction, The Pearls of Lutra is an absolute must. --Susan Harrison
