5. Amanda McKittrick Ros
Most of the writers on this list are at least enjoyed by people, hence their sales. Amanda McKittrick Ros is a bit different. Ros is considered to be one the worst writer in history. Her books are so bad they are actually funny. Mark Twain thinks her books are some of the funniest books ever written. The Oxford literary group "The Inklings," which included C. S. Lewis and J.R.R. Tolkien, used to read her work to see who could go the longest with a straight face. Her work is appallingly bad. Take for example that she calls pants "Southern necessaries." Or eyes are "globes of glare." "When their owners are unhappy, these globes are stuffed with sorrow." Pretty awful, right? The next logical question is how could someone like that get published and then get popular? First off, she published her own work. Secondly, to be honest with you, the answer of how she got popular, besides being so appallingly bad, is a mystery. Yet, she made enough money to buy a house with the proceeds from her first novel Irene Iddesleigh.
