Writer Paul Kupperberg started a series of posts last August about JSA: Ragnarok, a novel he finished in 2005 about the Justice Society. It was supposed to be published by iBooks before it went bankrupt in 2006. Since then, he's posted multiple excerpts from the book; check out additional ones here, here and the latest one here.

In that latest post, Kupperberg says efforts to get it into print still continue.
