Flame in the Mist is a sweeping, action-packed YA adventure set against the backdrop of Feudal Japan, where elements of the story of Mulan blend with the rich historical tapestry of the era.

The daughter of a prominent samurai, Mariko has long known her place. As an accomplished alchemist, her cunning rivals that of her brother Kenshin, but because she is not a boy, her future has always been out of her hands. At seventeen, Mariko is promised to Minamoto Raiden, the son of the emperor's favorite consort—a political marriage that will elevate her family's standing. But en route to the imperial city of Inako, Mariko narrowly escapes a bloody ambush by a dangerous gang of bandits known as the Black Clan, who she learns has been hired to kill her before she reaches the palace.

Dressed as a peasant boy, Mariko sets out to infiltrate the ranks of the Black Clan, determined to track down the person responsible for the target on her back. Captured and taken to the Black Clan's secret hideout, she meets their leader, the rebel ronin Takeda Ranmaru, and his second-in-command, Okami. As Mariko gets closer to the Black Clan, she uncovers a dark history of secrets, betrayal, and murder. Her quest for revenge leads to self-discovery and a confrontation with her deepest desires.
