No, no, no. I am not an agent. I am not an editor. I don't have any magic fairy dust that I can sprinkle on this man's manuscript to get it published (after what sounds like a decade of trying). (Full disclosure: if I had magic fairy dust, I would use it on me.)
If someone wants to pay me for a critique, that's one thing. But it didn't sound like this guy wanted a critique, even a free one. I think he just wants me to read it and see how wonderful it is and somehow ensure it gets published. The topic did not sound like anything I read OR write.
Anyone who makes a little effort can figure out who my agent is and query her if they think they have written a book that would interest her. (Full disclosure: she doesn't take on many new folks at all. So if she says no, don't take it too personally.)
I remember years ago, before I got published, I sat next to Elinor Lipman's cousin at a conference. Her first book of short stories had just come out. I wrote her a letter asking her advice about how to get published. She sent me back four pages suggesting I go to Bread Loaf and saying that her agent hardly ever took anyone new on. As predicted, I did query her agent, and the agent did say no. And I never went to Bread Load. Instead I sent out dozens of query letters.
A couple of years ago Elinor was in town and I came to her signing at my local bookstore. I showed her the letter. She didn't remember writing it, but she marveled that she had written four pages BY HAND.
People who want to get published should learn all they can about the publishing business. Then they can figure out who plays what role (and who doesn't play what role). Read Miss Snark's blog. Read every book you can get your hands on. (But check first on Amazon to see what kind of critical and reader reviews it's getting. ) You don't have to buy these books – go to the library. Just use Amazon to help you find them. Once you look up one book, you'll see what other folks who bought that book are buying, and you'll find other books to read.
Even as a published writer, I still read books on writing and publishing. I've read everything from The Complete Idiots Guide to Publishing to the Shortest Distance Between You and a Published Book. I leaf through writing magazines. I figure I can always learn something about craft, and writing, and the publishing business.
But don't think a published writer is going to help you get your book published.
