Path of the Assassin, Volume 15: One who rules the dark

Seems like an abrupt ending. I'd like to see the characters get older than they did. I suspect more was intended for the series, but it didn't get time to complete. I've read some more of the history of Ieyasu to try to get a better understanding of the series and it's a little disappointing not to see him later in life. (The series is largely fictional from what I can tell as far as the ninja/assassin material, but many of the political and warfare parts of it seem to be based off of actual history. ( )
