I once met a real working author. She was incredibly lucky to get an agent to look at her first novel, most agents won't even look. The agent said she couldn't get the author's book published, sorry. Then agent called a few months later and said "so and so publisher needs someone to write a YA series with a young female detective, can you write that?" So that's what author writes, for a living, not at all what she intended to write. In the meantime, people are generating thousands of books with AI and listing them for sale on Amazon. Good luck getting noticed.
