Codex Alera is a
fantasy book series by
Jim Butcher. The series chronicles the coming-of-age of a young man named Tavi in the realm of Alera, an empire similar to
Rome, on the world of Carna. Every Aleran has some degree of command over elemental forces or spirits called furies, save for Tavi, who is considered unusual for his lack of one. As the aging First Lord struggles to maintain his hold on a realm on the brink of civil war, Tavi must use all of his intelligence to save Alera.
