I learned from a writer/freelance editor that some agents now require chapter outlines as part of the submission package, in addition to the query letter, synopsis, and specified number of manuscript pages.
Chapter outline: single or double space? A few sentences per chapter or major plot points as bullets? Or a summary paragraph per chapter?
I'll have it in my toolbox if needed.
I've never heard of this for novels.
Non-fiction sure, but for a novel?
The first question you need to ask W/FE is "who asked for that" and get actual data.
And then think about this: most novels have DOZENS of chapters.
Non-fiction may have 20; I've sold books on proposal that have had as few as 10 chapters.
But outlining 48-100 chapters is nuts.
It's like a synopsis on steroids.
And I've never had an editor ask for something like this for a novel. Synopses sure, but never chapter outlines.
So, let's verify that someone actually did ask for this.
Then let's just all agree to say "naaaahhh"
Cause this is insane.
