“It’s good, but we can’t market it. If you were already famous in some other way so we could sell based on that, we would buy it.”
Could have phrased it better, but I kinda get it.
“It’s good, but we’re bad at actually selling books so we need you to be famous in another unrelated way to compensate for our incompetence”
FTFY
No you didn’t. People don’t buy the memoirs of random people. The publisher can move heaven and Earth but people still wouldn’t change the fact that the audience will never exist
So you run it by James Paterson, Inc. (or the estate of Tom Clancy or whoever fits best) get his name above yours and now you’re contracted to release new novels at an absolutely breakneck pace, but you have your foot in the door and can become the more famous writer who can release their own novels.
