For [manuscript] submissions, I’m pretty certain that writers assume that if the writing is good, an agent is going to be interested in offering representation to the author.
No doubt–good writing is essential but as an agent, I’ve passed on any number of submissions that exhibited some stellar writing. Why? Doesn’t talent trump all? Nope.
The #1 reason I pass on manuscripts with good writing is because of a lack of pacing.
Kristin Nelson on speed.
Incidentally, “pacing” is almost always code for a story being too slow, not too fast.
