Even if you weren't forced to read it in school like most people, you've heard of "Moby Dick." It's one of the most famous stories ever written. And when it was published, it completely tanked. Author Herman Melville was so disillusioned with his novel, he wrote a whole new novel about how bad he felt about it.
How bad did "Moby Dick" do in 1851 when it was published? It didn't even sell the entire first printing order...which was only 3,000 books. That's not many copies for a book that's passed out in schools every single year. Herman Melville was bitterly disappointed by this failure. In fact, he wrote mostly poetry and short stories after his novel about the whale, because he was so sad that so few people purchased it.
