And this describes the writing of Bill Crider. His body of work stretches from Mystery and Western to Horror and Science Fiction. From adult mystery to children's fiction. Bill is Chair of the Division of English and Fine Arts at Alvin Community College in Alvin, Texas. Book editors' offices are stacked high with manuscripts.
Magazine editors receive huge bags full of manuscripts every day.
Good manuscripts, even excellent manuscripts, are sometimes rejected because of the sheer volume that editors have to deal with. So no matter what anyone tells you, luck does play a part in getting published. I've been to a number of workshops where unpublished writers express the concern that some publisher will steal their manuscripts or ideas. Don't worry about anything like that. As far as I know, and I've talked to many, many writers about it, it's never happened.
