Okay, so let's just say that... hypothetically, that I were in the situation where I was fifteen-or-so years old and finished writing a book. And let's also assume that this book had been edited and re-edited several times, along with positive reviews from both peers and experienced teachers. If I sent a literary agent the manuscript along with a query letter saying that I was only fifteen/sixteen, would he/she honestly take me seriously? Would they even bother opening the envelope? Or would I be better off emailing a publisher directly?
