Dear Mrs. Snark, (uh..who?)
I secured an agent for my medical-thriller-type novel last December. He sent it out and it got 4 rejects. Based on the criticisms of the publishers who rejected the book, I made some changes and sent it back. Now he wants more changes - many that I don't agree with. Can I refuse to make the changes? If so, will he terminate my contract? Of course, he made the suggestions by email and I plan to discuss with him over the phone. But I wanted your advice: Can my agent make me change my book?
Did this medical thriller involve the surgical implantation of a clue?
"Make me" has the ring of "you're not the boss of me", and you're quite right. Agents aren't the boss of you. They don't own your work and they can't force you to do anything including follow their advice.
Not even Miss Snark can make you do that.
She can however insert clues without benefit of anesthesia. Step right up for a demonstration.
