WELCOME BACK! I love hearing folks tell me they’ve come back to comics thanks to the digital stuff. But head to a comic shop now and then—they’re awesome! :)
Anyway, you came in at the right time! We recently kicked off Marvel NOW! with tons of new #1 issues that are perfect jumping on points for readers new and old. Visit now.marvel.com to get tons of info and also check out the bestselling area for digital comics to see some of the books that other fans are going nuts for. Most of these series are up to issue 5 or thereabouts, so it’s easy to dive in.
Off the top of my head, I’d say you have to read Thor: God of Thunder, All-New X-Men, Iron Man, Avengers and New Avengers. But, also, all the others. So many good books right now.
