The most common thing I do for my clients (I'm a book doctor) amounts to extensive revision letters on their manuscripts. (darcypattison.com)
I don't consider it a failure to get a long revision letter — to me, that external guidance makes a good book great. (killzoneblog.com)
I also have ample experience in working with authors after they've received an agent Revision Letter — so if you have one in hand and are trying to figure out exactly how to revise, please contact me. (inkslingerediting.com)
