Two intergalactic mercenaries accidentally free a ruthless dictator from a maximum-security prison planet. Now, they must work with the authorities to get him back or find themselves locked up instead.--Publisher.

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.

"The expedition outside the wall was Eren's chance to prove himself. But it failed, and the female Titan is free once more! With his squad dead, Eren faces a royal summons. Will Mikasa and Armin have to betray their king to save their friend? And can they discover the female Titan's identity before she kills again?" -- From publisher's web site.
