The Blackfire Blade

the long version

Winter has come early to Korslakov, City of Spires, and Lukan Gardova has arrived with it. Most visitors to this famous city of artifice seek technological marvels, or alchemical ingenuity. Lukan only desires the unknown legacy his father has left for him, in the vaults of the Blackfire Bank. But when Lukan's past catches up with him, his key to the vault ends up in the hands of a mysterious thief known only as the Rook. As Lukan and his companions race to recover the key, they soon find themselves trapped in a web of murder and deceit. In desperation, Lukan requests the help of Lady Marni Volkova, scion to Korslakov's most powerful family. Yet Lady Marni has secrets of her own. Worse, she has plans for Lukan and his friends. Plans that involve a journey into Korslakov's dark past, in search of a long-lost alchemical formula that could prove to be the city's greatest discovery . . . or its destruction.
