Ah, another book finished and approaching publication, and of course the editor asks for endorsements.  Hmmmm.  I have many great author friends, but most of them are besieged by other authors to endorse their books.  I’ve been fortunate to secure one or two, but where do you go to get a major endorsement?  Sometimes your agent can suggest endorsements from her other authors, as mine did, and sometimes you can take a chance and write to a well-known author.  I was fortunate to have T.Davis Bunn endorse “Martha” in exchange for a small favor I did for him at a conference.  Jerry Jenkins has been a speaker for our Guild several times, but an extremely busy author, so he kindly opted out.  My editor sends out review copies and has done blog tours, which give excellent feedback.  Those can be used also.  Sometimes an author will do an endorsement for your book in exchange for an endorsement on their book.  I’ve done that also.  All that said, the ones that thrill me the most are from my readers.  It keeps me writing!
