"Centuries ago, summoners of the ancient empire transferred their collective knowledge into a giant, organic super-computer--the Encycopedia Verum. Now, Lord Duran, agent of chaos, has tapped into it, seeking control over all the world's creatures. But the great blue dragon that was enslaved to guard the Encyclopedia is nursing a grudge. With Kasche and friends outnumbered against Duran's forces, their only hope might lie with unleashing her--the most dangerous creature ever summoned."--Page 4 of cover
