Attack on Titan guidebook - Hajime Isayama

In this post-apocalyptic sci-fi story, humanity has been devastated by the bizarre, giant humanoids known as the Titans. Little is known about where they came from or why they are bent on consuming mankind. Seemingly unintelligent, they have roamed the world for years, killing everyone they see. For the past century, what's left of the human race has hidden in a giant, three-walled city. This is the definitive guide to the secrets of the Attack on Titan universe. A single volume of nearly 400 pages, including more than 16 colour pages in the centre.
