TCB, there are no rules at this point - if you like dialogue, write dialogue. But remember, the joy in writing fiction is description - what are people wearing, what are the surroundings, what are the details. That's what I didn't understand at first, when I began Benjamin Kritzer - but my muse Margaret kept asking what people were wearing, what did this look like or that look like and that became my favorite thing - to write that stuff and evoke and make that interesting. All my books are dialogue heavy, but I take some pride in the chapters that have little to no dialogue or where I go pages without any. Just keep writing - even if you haven't found the form or style at some point you will and as I always say, the book will start writing you. With Benjamin Kritzer, I had no idea of the form until halfway through part one, when I wrote an anecdote about this girl I'd liked in the fourth grade. It was as it had happened in life - brief. But when I read it the next day I knew I'd just found the form of the book and its plot - and I just moved that to part two and it became the entire point and purpose of the book. I had no way of knowing that until it presented itself.
