Hello! By way of background, I never got to read comics when I was a kid, because my conservative stepfather wouldn't allow it. Now, at the ripe old age of 31, I'm finally getting into it. I've spent a few years reading a variety of one-shots (Superman For All Seasons, Red Son, All-Star Superman, among others) as well as a lot of Hellboy, but I've finally decided I want to get into reading the more regular DC stuff. I decided to get a start on New 52, but kinda let it slip for too long, and now I'm swamped with options.
A good friend of mine is an avid collector, and has given me his entire collection to date to read through - I started with Justice League, but couldn't help but notice that it seemed to hint at there being other books I should have read in sync with them at the same time, along with little 'side issues' that were included, like the the SHAZAM tie-in.
So, here's my dilemma - is there a reading order, or any specific issues that have a preferred reading order, in order to ensure I don't miss anything critical?
Thanks in advance!
