Can the familiars bring magic back to the queendom? Vastia is in a state of war. Led by the evil Paksahara, whose command of the Shifting Fortress gives her nearly unstoppable power, an army of undead animals is wreaking havoc on the queendom. With human magic still gone, it's up to the three prophesized familiars—Aldwyn, Skylar, and Gilbert—to capture the fortress and bring Paksahara down. But it won't be easy. The three familiars must embark on a quest to gather seven descendants of the most ancient and powerful animals in Vastia. And to make matters worse, Aldwyn finds a troubling scroll that causes him to doubt the very truth of the prophecy that guides them. With inventive magic, epic action, and laugh-out-loud humor bursting from every page, circle of heroes is an extraordinary adventure you won't want to see end.
