OVERVIEW
Captain Cold frees Wally West, the Flash, from jail, and the two explore the mirror universe they've been thrust into. While Wally is talking with Joan, Captain Cold steals a book called "The Death of the Hero" by John Law. Among other things, it tells of the short-lived JLA and how Aquaman was killed by Starro. After Aquaman's death Aqualad formed the Titans, who were pretty much killed off by Mr. Twister. Just as they figure out who is responsible for throwing them into this other universe, the police, including Barry Allen, arrive.
COMMENTS
This isn't the worst of a multi-part story. While it doesn't make perfect sense, it can be read alone and understood. The whole reason for getting it (in my case), was the cover. Can't resist a cover in which heroes are burying Aquaman.
In this mirror universe, there was never any speedsters, and so the world was changed significantly from the DC Universe. Aquaman died because, apparently, the Flash wasn't there to guard his back. Aqualad died because Kid-Flash wasn't around. The JSA helped Nuke Germany when Mr Terrific was killed in World War II. Eventually the heroes started killing villians, and the police followed suit. No such thing as a fair trial in this USA.
CONCLUSION
Probably would have been better if I'd read the other parts.
