 Sims said it was far from the best work of Wolfman and Pérez; however, he still thought it was groundbreaking, saying, "It's the first time in comics history that EVERYTHING was in danger".A novelization of "Crisis on Infinite Earths" was written by Wolfman and published by iBooks in 2005, with cover art by Pérez and Alex Ross.The book follows the events of the original series; most of the story is presented from Barry Allen's point of view, while parts where he is not present are told from a third-person perspective.
