Grant Morrison's incredible run on JLA continues in this new hardcover.
First, the JLA's very first foe, Starro the Conqueror, returns in a new guise as the Star Conquerer! The JLA is powerless to awaken a slumbering world trapped in the endless nightmares caused by the menace formerly known as Starro. But help arrives in the form of an unexpected ally: Daniel, The Lord of Dreams, from the pages of THE SANDMAN. And in the tale "Crisis Times Five," the Justice League of America meets the Justice Society of America as only Grant Morrison can write it!
When Earth is threatened by beings of seemingly unlimited power -- beings reminiscent of the genies, and fairies of ancient myth -- members of both the JLA and the JSA rush to answer a challenge that may be beyond their power.
