Captain’s Fury is the fourth book in Jim Butcher’s fantasy series, Codex Alera, and the sequel to Cursor’s Fury.

Tavi is still undercover as the captain of a legion fighting the Canim invaders; an ambitious senator arrives from the capital to take over. Tavi finally comes into his own, learning that he is Gaius Octavian, the hitherto un­sus­pect­ed son of the First Lord’s long-dead heir. Far to the south, Amara and Bernard accompany the First Lord, Gaius Sixtus, on a secret mission, walking into the rebellious Kalare. Their journey bears not a little re­sem­blance to Frodo and Sam’s epic walk into Mordor.

The intrigue and the action come thick and fast, holding our attention to the end.
