I'm new to comics and I recently got the JMS Thor omnibus. I started reading it last night, can anyone lay down the basic premise of what happened to Thor before the 3 year hiatus? It's getting referenced a lot in the book and while I understand that he was effectively dead I feel I need a better understanding to appreciate the story more.
My actual question is can anyone recommend a good starting place for the Fantastic Four for someone new to the series? The JMS omni collects two Fantastic Four issues and although a short introduction I quite liked the characters and would like to read more.
