It’s disappointing to hear that traditional publishing might not be all it was cut out to be any more! My writer friend Tanya R Taylor (Author of "Cornelius" - Amazon #1 Best-seller in Teen & Young Adult Multigenerational Family Fiction) shared some information she found on the web from another author, who says she was traditionally published for several years with a very large publisher. Tanya reports that this author got decent advances, but did encounter some problems. One of the books didn’t do as well, because somehow a retailer ordered it from the wrong publisher and no one noticed the book wasn't being carried by the retailer until release day. Then another retailer told the author’s publisher they would no longer be carrying their midlist authors, only the New York Times bestsellers.
Tanya says the author went on to be self-published and apparently sales are steady.
