Ok cool.. It seems people are interested..
So.. let's start with some suggestions..
I'm eyeing, Yakuza Moon_ Memoirs of a Gangster's Daughter  by.. Shoko Tendo.. 
Synopsis:   Born into a wealthy family of a Yakuza Boss, Shoko delineates her turbulent life with a string of abusive lovers and her surreal struggles.
I think we should keep to "shorter" books.. because it takes a really long time to read leviathan class books as a group.
