There are five books within the series.

ACROSS THE NIGHTINGALE FLOOR:
In his black-walled fortress at Inuyama, the murderous warlord, Iida Sadamu, surveys his famous nightingale floor. Constructed with exquisite skill, it sings at the tread of each human foot. No assassin can cross it unheard. Brought up in a remote mountain village among the Hidden, a reclusive and spiritual people, Takeo has learned only the ways of peace. Why, then, does he possess the deadly skills that make him so valuable to the sinister Tribe? These supernatural powers will lead him to his violent destiny within the walls of Inuyama - and to an impossible longing for a girl who can never be his. His journey is one of revenge and treachery, honour and loyalty, beauty and magic, and the passion of first love. 
GRASS FOR HIS PILLOW:
'The most compelling novel to have been published this year' The Times
Takeo begins his training with the Tribe, who are determined to make him their most deadly assassin yet. As his extraordinary skills develop, he begins to discover more about these people, his adoptive father Otori Shigeru - and his own identity. Most chillingly of all, he learns that if he takes up his inheritance as leader of the Otori clan, the Tribe will hunt him down forever - perhaps even kill him. Meanwhile, far from her lover, Kaede becomes central to the power-broking played out between the clans. Can she, as a woman, take control of her own future, and use her intelligence and cunning to assert herself in this world of all-powerful men? And will the fated lovers be forever separated? Weaving the same magic as Across the Nightingale Floor, Grass For His Pillow is just as powerful, just as exciting, and just as fascinating. Lian Hearn's claim to classic status is confirmed once again with the second book in this extraordinary trilogy. 
THE BRILLIANCE OF THE MOON:
Takeo and the exquisite Kaede, still only teenagers, are now married, but the implacable forces of destiny that rule their lives tear them apart. Takeo, a battle-hardened warrior at the head of an army fighting for his Otori birthright, finds his courage and leadership forged in the fire of bloodshed and sacrifice, while his legendary magical powers are tested to their limits against the invisible assassins of the Tribe. Kaede, determined to reclaim her own lands, is treacherously betrayed and forced into marriage. Their love will survive until death – but death, in this savage, beautiful world, is always only a moment away. 
THE HARSH CRY OF THE HERON:
Takeo and Kaede have ruled the Three Countries peacefully for over 16 years, following the tumultuous events laid out in the epic Tales of the Otori. The land and people are peaceable and calm, the world is balanced and Heaven seems to shine upon them. They have three daughters. Shigeko, 15 years old and heir to the vast territory, is developing into a bold warrior with meditative powers, making her wise beyond her years, and Maya and Miki - twins, two years her junior - have inherited the supernatural powers of their father. However, an attempted assassination of Kaede at the New Year ceremonies reveals that the inescapable forces of destiny still bear down on Takeo and those he loves, and that forces from his past and from beyond the Three Countries are plotting. While his strength and power come from the enduring love of Kaede, the blind sage's prophecy that only his son could bring death to him, haunts his thoughts. The last book,
