If I understand it right, and not claiming I do after all for all the years I have been reading comics I still do not know much about the behind the scenes, anyhow this is the lead in to DC's big summer event. Or the first of the big summer event. In any case whatever this series is even someone as ignorant as myself when it comes to comic production behind the scenes can tell its Big! Some of the biggest creative minds in the industry are working on this as a look at the credits will tell you.
Not only are the creator's an all star list, but so too are the characters appearing in this book. The opening panel has Hawkman, then of course there is Batman and Superman. Aquaman and Green Lantern. And some cameos I do not want to spoil.
In short the plot revolves around a mysterious element or metal Batman has been investigating. That is all the summary I will provide as I really want this review to be as spoiler free as possible.
Suffice it to say with all the famous creators working on this both the story and art are fantastic!
