Do not buy this. Over half the book consists of interviews with creators of Marvel comics about events that have now already happened. The only really interesting inclusions are Secret Invasion: Dark Reign and Dark Avengers 1, both of which are collected in more worthwhile trades. If you care about these big events, you are probably already reading the fabulous New Avengers, penned by Brian Michael Bendis. Volume 10 of the New Avengers collections contains Secret Invasion: Dark Reign, as well as several issues of New Avengers. And it's cheaper than this!
If you are interested in following the dastardly exploits of Norman Osborn, you may be interested in Dark Avengers, also by Bendis. It's almost a companion to New Avengers, as there is a fair amount of interplay. Volume 1 contains, of course, Dark Avengers 1.
So there you go - don't buy this, buy one or both of those books. For me, Bendis is the best Marvel scribe of the current day, and New Avengers is the best title. I enjoyed Dark Avengers as well, more than I thought I would.
