Some solid, classic comic adventures starring, who else, Superman and the Justice League! Very little previous comic-reading knowledge is necessary for this one, although it might help to know the members (listed below.) Not your classic Justice League here, but more the goofy, somewhat dysfunctional Justice League International members here!
This book starts off a new run, I believe, of the JLA. At the beginning of the book, characters reveal that the JLA was disbanded by the UN or something, so there is no super-team to address threats. But one thing leads to another, and the heroes band together to form a new one anyway.
This time it's really more like the JLI, though, since the members are mostly the same: Booster Gold, Blue Beetle, Guy Gardner, Fire, Ice, and then newcomers Maxima and Bloodwynd. Batman gets a reluctant Superman to lead the team, but at least in this volume he's not always around. If you've read JLI collections before, you're probably familiar with the goofy, bickering, and generally "carefree but still devoted to being heroes" attitude of the JLI, and it's kind of hilarious to see Superman dealing with it (especially since he's not enthusiastic about being a team player... trying to control Guy Gardner is no one's idea of a good time.)
We also get some peaks at Max Lord, working with Oberon for some reason, and still trying to weasel his way into controlling the JLA. Superman's not for it, but he slowly gets in there anyway.
Overall, the collections in this volume are good for a fun, light read. I'm always up for some Blue and Gold, Fire and Ice, and Guy Gardner and whoever he doesn't like this week. If you enjoy the JLI or lighter comic fare (especially if you don't really know too much backstory), give this volume a try.
