The betrayal of the living - Nick Lake

Taro is at a crossroads: He has vanquished Lord Oda for good, but with no land
and no title, he has no hope of marrying Hana, the daughter of a daimyo.
So when Taro receives news of a murderous dragon and the large reward for
killing it, he and his friends find themselves on a dangerous quest to slay the
beast.Their mission has the potential to save the people of Japan - but
failure will result in the deaths of thousands. And dragons are not the only
monsters they will encounter: The dead, led by the odious Kenji Kira, have begun
to rise, and they have Taro in their sights.In this heart-stopping
conclusion to the Blood Ninja trilogy, the future of all feudal Japan is in
danger, and everything Taro holds dear will be threatened. But it is the
betrayal of flesh and blood - his own flesh and blood - that may be his
ultimate undoing.
