Mike Nelson, author of the popular on-line novel Dingo (really, you should be reading it. It is packed with remarkable ass-kickery) is doing a new book for Boom! Studios.
Mike explores a very simple idea. Say that the aliens who invaded in War of the Worlds, who were smart enough to pull off interplanetary war, suddenly licked the whole "oooo, wet coughs, didn't think of that" hink.
They're back. And they are very, very pissed. Read about War of the Worlds: Second Wave at Newsarama.
