Keiko thought she was becoming a true samurai warrior, but the loss of her sister will make her doubt everything.

Keiko's revenge on her enemies is almost complete. Like the chameleon, she has changed herself to attract and entrap the men she seeks. Now, just one man remains unpunished. But before she can complete her vengeance, karma destroys her plans cruelly.

Niko--her adopted younger sister--is kidnapped.

Keiko is sure she knows who is behind the abduction, but she cannot act alone to get Niko back. She is forced to turn to the most unlikely ally to help her--Akira, the most feared yakuza in Edo.

Putting her own desires aside, Keiko must question her own motives and role as a samurai to keep from losing the only person left in the world who loves her.
