Not thinking of writing for young children. More interested in writing for teens and young adults. Thought I would model my books on the books I've read for teens and young adults, but when I sent the work to the publishers, they told me it wasn't fit for publication into their catalogues. So I guess there were problems either with my writing style, or about the themes I mentioned or the way I treated them or because it was too long... Anyway, if I'm planning of writing for teens and young adults, what should I watch out for, and from where should I start to research from? Style, language, themes, lenght, taboo arguments...? This is just to get me started, to get the generel idea. I'm also planning on reading how-to books on the subject.
