When time itself comes under attack, it will take the combined efforts of history's greatest heroes to save the entire DC Universe!

EVERYTHING YOU KNOW ABOUT THE DC UNIVERSE IS UNDER ATTACK.

THE UNIVERSE WILL BE SHAKEN TO ITS VERY FOUNDATIONS...

AND THEN REBUILT.

In 1985, DC Comics dramatically altered comics' original universe with Crisis on Infinite Earths--an unforgettable, defining event in comics history that streamlined the DC Universe continuity. Nine years later, the heroes of the DC Universe found the temporal fabric of their new reality unraveling, and the biggest threat since the Crisis was about to be revealed in Zero Hour: Crisis in Time.

When time itself comes under attack, it will take the combined efforts of history's greatest heroes to save the entire DC Universe. A catastrophic temporal distortion is creating chaos across the past, present, and future, leaving puzzling alterations and anachronisms in its wake. As villains across time rise to take advantage of the disruption, it's up to a team of time-tossed heroes to uncover the true mastermind behind the crisis before the universe itself is destroyed. Win or lose, the history and future of the DC Universe will be forever altered!

From comics legends Dan Jurgens and Jerry Ordway comes Zero Hour: Crisis in Time, one of the most all-encompassing events to ever hit the DC Universe. In this omnibus edition, every chapter in the groundbreaking saga is presented in chronological order for the first time ever, including well-over a dozen never-before-collected issues. Featuring a legion of heroes from the iconic to the obscure with an all-star cast of writers and artists, this watershed event left its mark on the DC Universe for years to come.
