For autumn 2026, Super Thursday will take place on October 8, marking the single biggest release day of the year for autumn books, featuring thousands of titles timed ahead of the Christmas shopping season, but the flurry begins in September. Here are just some of the books which you may be bagging from the bestseller stands this autumn:1. This time it’s a set of short stories to tide fans over before the arrival of Book Four. It features good-natured dreamer Batter Gray who believes his future lies in poetry and joins a prestigious poetry journal called Peck & Peck, where he tries to navigate the two very different editors in chief and their associates. It’s Waterstones’ number one pre-order for all autumn books and is the first new Gruffalo story in more than 20 years, introducing Granny Gruffalo as she visits the family in the forest, full of all the original characters you know and love.
