Log Horizon, Vol. 10 (light novel): Homesteading the Noosphere — Mamare Touno

Nearly a year has passed since the Catastrophe, and it seems like no one is any closer to figuring out what exactly happened. But when Minori brings a letter from Roe2, the explosive contents rock Shiroe to his core! These revelations arrive just as an impending war threatens to consume Yamato, forcing every adventurer to decide whether to search for a way home or to throw themselves headfirst into a bloody battle alongside the People of the Earth. Whatever their choise, those hiding in the shadows won't wait before making their moves!
