Since the last I posted I have one addition to the list: R. Scott Peoples.  Also, Jennifer Weiner has a new book out.

Here's the list I've been keeping of books by Kossacks, former Kossacks and Kossacks-once-removed.  I'm only listing the dkos ID if the author has outed himself here or if they have informed me directly they don't mind being outed.  You can reply to this with more entries or email me them at: sarahnity (at) gmail.com
