Furies of Calderon is the first novel in the high fantasy series Codex Alera by Jim Butcher.

The novel was well received, with critics praising Butcher's turn at a more traditional fantasy setting, fast pacing, action, and his characterization of the antagonists.

A young woman named Amara travels with her mentor Fidelias as part of her graduation exercise.

They infiltrate a camp of mercenaries, when Amara is tricked by a watercrafter named Odiana and betrayed by Fidelias.

The story switches to a steadholt controlled by Bernard, a man who lost his wife and children and stays with his sister Isana, and their nephew Tavi who is furyless.

Aldrick kills Kord's son Bittan and after arriving, Isana floods the river.

Bernard and Amara become Count and Countess of the garrison, and Isana is given the title of Steadholder, making her the first woman ever to own a steadholt and gain citizenship through merit rather than marriage.
