Attack on Titan / Isayama, Hajime

"Hange's interrogation of a Military Police squad has revealed that Krista (a.k.a. Historia Reiss) is the true heir to the throne. The Corps quickly moves to enthrone her as queen, but a homicidal MP leads a squad that abducts Eren and Krista and the throws the Corps into disarray. With Erwin arrested and the Survey Corps on the edge of dissolution, are Levi and Hange finally out of options?"--Back cover.

"Commander Erwin has finally come to a decision: Putting their own wealth and position ahead of the survival of humanity, the royal government is no longer fit to lead. To execute their leader's most audacious plan yet, Eren and Krista will have to put themselves in peril yet again, and Armin, Mikasa, and the rest of the Survey Corps will have to turn from humanity's guardians into traitors. If they fail this time, they'll face not a Titan' gaping mouth, but the gallows"--Back cover.

"With no combat gear and Wall Rose breached, the 104th scrambles to evacuate the villages in the Titans' path. On their way to the safety of Wall Sheena, they decide to spend the night in Utgart Castle. But their sanctuary becomes a slaughterhouse when they discover that, for some reason, these Titans attack at night!" -- from publisher's web site.

"The young Erwin Smith is a rising star in the Survey Corps, humanity's only hope of defeating the man-eating monsters known as Titans. Ruthless and dispassionate, Erwin's mind is devoted to strategies and intrigue. But beneath Erwin's feet is another world, the Underground, where humans are born and die surrounded by the garbage the Capital throws away. Here, the criminal Levi survives on his wits and agility. But when these two ambitious men cross paths, who will prove himself stronger?"--Page 4 of cover.

Eren's arrival helps the 104th claim victory at Wall Rose, and the identity of the two Titans destroying the walls is revealed.
