Short story – up to 7,500 words in length. Usually listed for $0.99
Novelette – 7,500 to 17,500 words in length. Usually listed for $1.99
Novella – 17,500 to 40-50,000 words in length. Usually listed for $2.99 to $3.99
Novel – Over 40-50, 000 words in length. Usually listed for $4.99 or higher
I try to keep my book prices as low as I can, because of the economy. It’s hard these days and since I love to read too, I understand this.
Many people who know I write always comment, “Authors get rich with the prices they list for their books.” It doesn’t work that way. The author gets a very small percentage of the list price of the book. It’s our love to write and our readers that keeps us writing.
Bless you and love you all,
