Captain's Fury:
Tavi of Calderon, now captain of his own Legion, has been fighting a bitter war for two years. Then he discovers the invading Canim warriors are harbingers of a far greater threat. The Canim are being hunted in their turn by a savage race that forced them from their homeland - and which has pursued them to the Aleran borders. With options fast running out, Tavi proposes an alliance with the Canim.But the Senate's new military commander wishes only to wipe out the Canim 'scourge', and would also kill Aleran slaves that have sought freedom with these aggressors.

First Lord's Fury:
The aging First Lord of Alera has fallen in battle. Yet his people must continue to resist an invading inhuman army. Desperate Alerans even pledge fealty to the Vord Queen to survive, turning the incredible power of Aleran furies back on their own people.

Cursor's Fury:
Power-hungry Kalare has rebelled against Alera's aging First Lord, Gaius Sextus. Ill-equipped to face this attack, Gaius must seek support - even from the combative High Lord of Aquitaine. Kalare has also seized valuable hostages that could mean the difference between victory and failure. And Amara, the First Lord's Cursor, has been tasked with their rescue.

Furies Of Calderon:
For a thousand years, the people of Alera have united against the aggressive races that inhabit the world, using their unique bond with the furies - elementals of earth, air, fire, water and metal. But now, Gaius Sextus, First Lord of Alera, grows old and lacks an heir. Ambitious Lords manoeuvre to place their Houses in positions of power, and a war of succession looms on the horizon.
