You’re an author. You can write any book you choose. Inevitably, you’ll get ideas for books you wish you could write, but the big rule is “write what you know”… isn’t it?
If everyone stuck to that rule, there’d be very little science fiction, and few mysteries. You can write any book you can imagine, and can research.
I released Fiction Frenzy in time for NaNoWriMo, and several writers have asked me about writing various kinds of novels.
They're stymied by "write what you know."
As I said in the above article, you can write any book you can imagine, or can research.
