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.
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.
