The Dark Knight has faced many twisted nightmares: killer clowns and crazed ex-D.A.s, women dressed as cats and steroid-pumped madmen. But an unholy relic -- the bones of Hunter Rose -- has brought a deadlier foe to his city. A relentless, merciless foe. A foe known as Grendel-Prime. The devil has returned to Gotham.

Follows first Batman/Grendel miniseries, as well as Grendel: War Child.
