Yes, the story is convoluted. That's almost to be expected when you have more than one author; here, we're gifted with novelist Brad Meltzer and comic writer Geoff Johns. The story involves three super teams: the Justice League of America, the Justice Society of America, and the Legion of Super-Heroes (from the 31st century). Seven of the Legion have been trapped in time in different areas and it's up to the JSA and JLA to determine where and why. The artwork by Ed Benes is terrific, and the ending is worth it. Also, pick this up for one of the best written and illustrated comic stories ever: "Walls" by Brad Meltzer with claustrophobia-inducing pictures by the very talented Gene Ha.
Re-read in 2016: This is a strange story. Brad Meltzer, Geoff Johns, and several good artists and pencillers worked together on it, but in the end, it’s a bit confusing and unfulfilling.
There’s no villain in the story, but midway through, we get a panel featuring three of DC’s worst (including the Ultra-Humanite and Ocean Master) and then they are never seen nor heard from again. Why?
The story begins with a man named Val Armorr, who is a member of the Legion of Super-Heroes, a 31st century band of teenagers with special powers. He’s trapped in this timeline with seven other members of the Legion, and the JLA and JSA must find them all and see what’s going on.
And that’s part of the major problem. We’re never sure what’s going on. We know they’re here and we’re told that they’re trying to save someone (or something), but nothing is fully realized or explained. The fun comes in watching the two superhero groups team up. The ending is pretty good, but overall the story falls flat, and that’s surprising when it’s coming from two great writers.
The standalone story “Walls” is one of the best I’ve read (Brad Meltzer wrote this one), and the artwork is amazing. It involves Red Arrow and Vixen being trapped in a collapsing (or collapsed) building. Gene Ha’s work here is terrific. Get the book if only for this story.
The other two stories, “Monitor Duty” and “Yesterday, Today, and Tomorrow” show the JLA as more of an extended family than a group of superpowered beings. They eat, play, laugh, love, and fight with each other regularly. They also routinely save the universe. The latter story shows the growing bond between Clark, Diana, and Bruce and how this bond is nearly severed. All in all, a good read for those who love the JLA.
