World without Superman tie-in - The Sleepers: Part 1 - Written by Greg Rucka. Art by Eddy Barrows and Ruy José. Cover by Andrew Robinson. To give the full details of this story would spoil the dramatic finale of the 'New Krypton' crossover, and we don't want to do that! Suffice to say, a 'World Without Superman' is a very dangerous place, indeed, and the only thing standing between the good (and not so good) folks of Earth and an impending shadow of doom are the all-new Nightwing and Flamebird! 36 Pages, Full Color. Cover price $2.99.
