The spellbinding conclusion to the brilliant fantasy series by the author of The Mirador and Mélusine.

Exiled from Mélusine for the crime of heresy, the once powerful Cabaline wizard Felix Harrowgate and his half-brother Mildmay, former cat-burglar and assassin, journey to Corambis to face judgment from a ruling body of wizards. Corambis, however, is a land plagued by civil strife. Kay Brightmore, the Margrave of Rothmarlin, is part of an insurrection to restore the monarchy in the southern half of the country. In desperation, Kay and his rebels seek out the engine of Summerdown, an ancient magical device rumored to have terrible powers. Once the engine is awakened, only a powerful wizard can stop its awesome potential for destruction. Felix and Mildmay arrive just in time for their greatest challenge—and ultimate destiny...

The dashing wizard Felix Harrowgate has reclaimed his sanity, magic, and position in society. But even as he returns to his former place in the Mirador-the citadel of power and wizardry-there are many who desire his end. Mildmay the Fox is an ex-assassin, a cat-burglar, and Felix's half-brother. Tied to Felix by blood and magic, Mildmay goes where Felix goes-even into the Mirador. There, Mildmay finds himself drawn to an alluring spy of the Bastion, a rival school of wizards. The Bastion desires above all else to bring down the Mirador, and Felix is the key to its destruction. But Mildmay cannot let Felix stand alone, and will fight to save both his brother and his city from certain ruin.
