You are too busy to consider this novel. Never mind that it is the first in a series of loosely connected titles destined to spawn a cavalcade of big-screen adaptations; you are simply too busy. You don't have time to consider this project.
Your lists are already full. The market place is clogged as is and can scarcely hold another title anyway, regardless of how good the work is. Save yourself the time and effort, don't bother asking to read this novel. It will only upset you. The prose is good but a lot of good prose gets ignored every year and you're not sure you will be able to save this piece from the same fate. You're not sure if you possess the necessary skill.
Don't get angry with yourself. It's all right. It's OK. Not everybody was meant to be a superstar in the literary world. Don't get down on yourself because you can't sell my book. Look at the bright side; you haven't asked to read the manuscript yet so failure remains that far away.
