I've finished editing a book for a client and have been asked to make up a query letter for him. It's about a lonely, social outcast who starts to come out of his shell when his cousin introduces him to drug dealing, but of course it all starts falling apart when addiction strikes. It's gritty, depressing and has some hard hitting moral lessons without being in-your-face about it. He's a teenager, and it has a suburban setting. I have an idea as to what genre it falls into, but I'd love to hear an outside opinion to quell my doubts.
