Mélusine

Mélusine — a city of secrets and lies, pleasure and pain, magic and corruption — and destinies lost and found. Felix Harrowgate is a dashing, highly respected wizard. But his aristocratic peers don't know his dark past — how his abusive former master enslaved him, body and soul, and trained him to pass as a nobleman. Within the walls of the Mirador — Melusine's citadel of power and wizardry — Felix believed he was safe. He was wrong. Now, the horrors of his previous life have found him and threaten to destroy all he has since become. Mildmay the Fox is used to being hunted. Raised as a kept-thief and trained as an assassin, he escaped his Keeper long ago and lives on his own as a cat burglar. But now he has been caught by a mysterious foreign wizard using a powerful calling charm. And yet the wizard was looking not for Mildmay — but for Felix Harrowgate. Thrown together by fate, the broken wizard Felix and the wanted killer Mildmay journey far from Melusine through lands thick with strange magics and terrible demons of darkness. But it is the shocking secret from their pasts, linking them inexorably together, that will either save them, or destroy them.
