My memoir involves my experiences in music. The agent who wants to represent my work is passionate about my book, understands the concept and what I am trying to do, and all of his books are extremely successful. My only concern is that most of the books he represents are mainstream Christian. Although my book doesn’t fit anywhere in that category, this agent seems perfect for me in so many ways. His Christian books are all best sellers, so clearly this agent knows what he is doing in that area. Will he have the same pull with publishers in a book that is off his topic area?
If he's a good agent, he wouldn't offer to take you on without some idea of whom he was going to sell your material to. Ask him where he would try to sell it and what editors he knows. If he has a comprehensive response, he'll be a good agent for you. If he doesn't have a real plan and you have other options, go elsewhere.
