Knight Terrors Omnibus

"The heroic trinity of Batman, Superman, and Wonder Woman discover something terrifying in the Hall of Justice: a body of an early Justice League enemy. Their quest to unravel the mystery of this death leads them to a place beyond the land of the living and dead. This is a place called The Nightmare Realm, run by a powerful new villain, Insomnia, guiding heroes into their own personal and twisted nightmares. Can the unlikeliest of allies--Deadman--bring our heroes back to reality before it's too late?"-- Provided by publisher.
