I started writing a story originally just for fun, but it has grown & grown out of all proportion. I'm not even 20% of the way through & I'm now thinking of turning it into a book. How do I divide it into chapters? Do I write the whole thing & then divide it up or write it straight into chapters. The story means a lot to me as it comes from all the stories my dad told me of him being a child during the war & all of my family, my Uncles, Aunty & my grandparents. It's kind of a living tribute to them all as they are all no longer with us.
