Fumi Yoshinaga Ooku: The Inner Chambers Vol III
Awesome! Totally awesome! I picked these up at Wiscon and tore right through them. A wonderful manga, that won the Tiptree award this year. It's an alternate history in which a plague sweeps 17th century Japan, killing off 4/5ths of the men. Women take over, including the shogunate, and the young shogun must set up a harem of men to protect the palace and ensure an heir.
It's interesting, in that all the male characters in the series are either good or bad (so far,) but all the female characters are much more nuanced and complex.
Yeah, that's all I have to say about that. It's amazing. Read it!
