Back in March, Marvel announced that Angela, created by Neil Gaiman and appearing in SPAWN #9, would be making her way into the Marvel Universe. If you read AGE OF ULTRON #10, you have an idea how this becomes possible.
Angela will make her presence known in GUARDIANS OF THE GALAXY #5, written by Brian Michael Bendis and Neil Gaiman. Since this is kind of a big deal, you might want to pick up the issue.
If you're into variants and exclusive covers, Dynamic Forces is offer an exclusive variant cover, currently on pre-order for $14.99. The comic will later revert to the regular MSRP of $29.99 after August 1st. Oh, and the cover is by Mike Deodato. So that's pretty cool.

If you like the exclusive variants, they also have other comics such as X-MEN #1, X-FILES SEASON 10 #1, IRON MAN #9 Variant 9.8 CGC Graded, GUARDIANS OF THE GALAXY #1 Variant 9.8 CGC Graded and DANGER GIRL: TRINITY #1 J. Scott Campbell Variant.
