Della Galton's latest book, Moving On, does what it says on the tin. It explains in detail the differences between writing short stories and writing a novel, and it's not just about the length! It's a must-have for any short story writer who's thinking about trying a novel.
Using lots of examples, Della shows the differences between a story plot and a novel plot, and helps you recognise the form in which your latest idea would work best. She explains how important it is to really know your novel characters, why they need a full backstory, friends and family - even if you're not going to use this in the novel. She shows why using a single viewpoint is usually best for a story, while it could be too limiting for a novel. She covers beginnings, middles and ends, theme, structure and flashback and how their use differs depending on what you are writing.
The whole thing is written in Della's easy to read style, and comes thoroughly recommended by this writer. I just wish this book had been available a couple of years ago when I started writing my novel! I suspect I'll be referring to it a lot while I write the next one.
