The Crow in the Harem. Book 2

Deep within the palace chambers lives one known as the immortal demoness. Lady Crow must not get close to humans, but Shousyue breaks the unspoken rules: she takes in servants, helps the emperor, and grows closer to those around her in the palace. She cannot remain indifferent to the suffering of others, no matter who it happens to be — a mystical spirit, a ghost, or a person. One night, a terrible event occurs in the inner palace. One of the emperor's concubines is murdered. Lady Crow, trying to track down the murderer, accidentally discovers something that no one should know: the truth about herself and her abilities.
