Circulus de Potentia: Magicae Mathematica Volume 2

A festival in Nosaj's honor has been interrupted by a mysterious challenger wearing the Circulus de Potentia, a band of gold that gives him unstoppable strength and power. One by one the Guardians fall and a race is on for Alex to go find the wizard with a secret regarding the curious symbol on the golden band. Finding this peculiar wizard named Pythagoras wouldn't be such a daunting task if it wasn't for the packs of wolves that roam the forest and a maze she and her friends will have to solve as well as a riddle fashioned by Daedalus himself.

What awaits Alex in the Forest of Factors? Can Archimedes solve the equation in time? Can the Guardians stop this invincible challenger? A symbol unknown, a riddle unsolved, a maze guarded by a monster, a race against time to find the secrets of the Circulus de Potentia and the most precious thing in the world.
