Endangered is setting the stage for Prufrock's exploration of his past, his family and his origins. If you've been following since 2007 (as I have) then you're already hooked! If not, that's what the trades are for! There's a good interview with Grecian found here.
Endangered#1 also features a special biography section written by yours truly; keep your eyes peeled for more bonus features by me in upcoming issues of Proof: Endangered!
And, so long as you're at the comic shop tomorrow, be sure to grab the Official Handbook of the Marvel Universe A to Z Update#5, the last issue of the 2010 series! Learn more about its contents here!
