I'm kind of confused as hell while reading Avengers and New Avengers while trying to catch up to Secret Wars. Should I be reading them back and forth by publication date and are they both continuity wise taking place at the same time? Because Stark's whereabouts and pretty much everything in New Avengers going on kind of confuses me so damn much and I'm not sure how much of it I'm just overthinking.
I am doing the arc. You don't have to flip flop back and forth until Infinity hits. The prelude to infinity is pretty loose and serves as the lineup for the runup. Once Infinity hits you will want to follow the chart conveniently posted in the back.
I also found the Comicbookherald reading list to be very helpful, specifically going into the Infinity run here
Being new to Marvel it is still somewhat confusing but entertaining none the less. Things tend to happen on the macro level in these books.
