Read as single issues.
Apparently, here Captain America, Spider-Man, and Black Widow (some others, too, but those are the main characters in this book) die at some point in their respective pasts (Cap in the 40s, Spidey in the 60s, and Natasha...when she's pretty young) and turn up - at the same time - on a fantasy island in the afterlife where there are manticores and elves and orks and cat-people, oh my.
There they get involved with different factions that then go to war for some reason, which somehow leads to zombies (but not the Marvel Zombies that were so big a few years ago) and... - most of time I have no idea what is actually going on in this series or why anything that happens, happens.
Uncle Ben is an asshole, some other characters appear to be someone, but do not get conclusively identified and the ending is...yeah, what exactly...?
This was confusing as hell and not interesting enough to actually strain my tiny little brain for an explanation.
The artwork, though, is beautiful! Not only the covers, which are reminiscent of all those 70s sci-fi and fantasy mags, but the amazing interior artwork, too. Kaare Andrews draws the different characters in slightly different styles, which works pretty well. I do get why this miniseries got immediately reprinted in an oversized hardcover, but I don't just look at my comics, I read them. And there is just not enough of a coherent story here to justify that extra cost.
