Dear Miss Snark,
Supposed that the Gods smile upon me and my agent and my book sells well.
Given that, who pays my agent? Do I receive the check form the publisher and then write a check or does the publisher write two checks?
The publisher pays me and I pay you, less 15% for my work.
If you fire me, the publisher still pays me and I pay you, less 15%
If you have a new agent, the new agent sells new work, gets a check from the publisher and pays you. I still pay you for the book I sold.
