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. People believe their 100-metre-high walls will protect them from the Titans, but the sudden appearance of an immense Titan is about to change everything.

Thanks to Eren’s timely arrival, the 104th has managed to turn the tide at Wall Rose. But this momentary victory forces two more traitors into a corner – and the identity of the Titans who have been destroying the walls is revealed! What can Eren do against the two most dangerous monsters humanity has ever faced? And who else might be an enemy in disguise?
