There’s no one big “Eureka!” moment when writing a novel. Usually it’s a whole lot of little “huh”s. A really good book is often the ideas for five or six different books smooshed together. With that in mind, your daily writing challenge is to combine your efforts from three previous challenges.
P.S. Scott Westerfeld has just published a wonderful book called AFTERWORLDS which explores the journey of a teenage writer in the New York publishing scene. If you’ve made it to writing challenge 35, it’s probably your sort of book.
