Went to a publishing class last night given by an agent. The process send Querry letter, wait for reply, send a brief info packet and a third mailing includes sample chapters. get a contract(if your lucky) All this without a single word written for the story? From my pov, I have never been able to write a book report without reading the book. Well at least a very good one. How do you estimate how long the book will be if you haven't written it yet? Do writers actually wait to write until they have a contract, or do they write the book then send the querry letters out? It seems very weird to me to sign a contract with only a couple chapters written.
