In an alternate-world Italian Renaissance where the Italian states have formed a federation, the great epic poet Ludovico Ariosto is writing a fantasy adventure set in the New World that reflects the difficulties besetting his patron, Damiano de' Medici. While the Cerrochi in Ariosto's fantasy battle the evil wizard Anatrecacciatore with the help of a heroic version of Ariosto himself, politics and skullduggery plague the Florence-based court of Italia Federata, in which Ariosto becomes enmeshed when he chooses to support the Medicis against those seeking to fracture the Italian union.
