The book I'm most looking forward to is Minutemen, written and drawn by Darwyn Cooke. The lives of the first generation of costumed heroes—who were in a team called the Minutemen—in the Watchmen universe were only hinted at in the original masterpiece and this series will show more of their adventures.
S Kotaku's got an exclusive reveal of the cover for Minutemen #3 and it looks like the spotlight is on the Garbo-esque heroine called Silhouette. She might not make it to the end of the book alive, though. Minutemen #3 comes out this August.
