Don't be discouraged by the unofficial translations over at
Baka-tsuki. They are doing a fantastic job, having already translated two full novels and having various translations on over five. The fully translated novel pdf file's are quite easy to find, but if you ever need them you need only ask me.
The anime missed
alot, especially in regards to all the things that happened in the fourth novel "The Drugs and the Dominoes". Well the anime created this hurrendous "filler" 1932 arc in which the Runarata's strike a deal with Senator Barium in order to capture Dallas and experiment on him, which sufficed to say never happened in the canon novels.
The 1932 timeline was entirely different, for one thing it was a strait up gang war between the Runarata's and the Gandors over drug trafficking. Vino also shows up to fight Maria "The Mexican Assassin" (which is more win than you can imagine). Luck beats the crap out of Gustavo with his own broken limb.....
Yea the shit's pretty epic
