When you’re trying to write a book, it helps if you know what genre you’re going for.
I don’t know what genre my book is going to be in. When it starts, the main character is thirteen; later on, she’s sixteen going on seventeen (for the record, I hated that song). That doesn’t automatically mean the book will fall into the ‘young adult’ category, but it’s not going to be a deep soul-searching book either. At least, I don’t think it is. I plan for her story to continue into her early twenties, so that’s definitely not YA.
Let me have a think about what my target reader is going to be, and I’ll get back to you.
