Simon the fool, Simon the halfwit, Simon the lost is pursued across medieval Europe by a sinister league of conjurers, the Apostles of Light. Having erased his past, they will stop at nothing to steal his future. When he seeks shelter among the Knights of Palermo, a dubious band of wandering rogues, Simon attracts a mysterious young woman whose fate is somehow interwoven with his own. Caught in a struggle for power between the shadowy Apostles, his adopted Knights, and, a secretive cabal of powerful women, Simon explores his own dark past to find a road to survival. With only a broken sword and his own shattered memories, Simon must thread this maze of warring factions to discover who he was and why he is inexorably drawn to the haunted ruins of twelfth century Rome.
