It's that time of year. Journalists, reviewers and cultural pundits are making their selections of the year's best books. But we want to hear from YOU.
Which has been YOUR favourite book of 2018 - the one book you couldn't put down, haven't stopped thinking about, or couldn't wait to recommend to friends? We're looking for books that were published this year (from 1 January 2018) in either paperback or hardback, but won't be too precious about it.
Fill in the form below with your choice along with 100-300 words on why it's your book of 2018 and we'll share some of our favourites using #HayBookOfTheYear. By submitting your selection below you'll also be entering a prize draw to win a festive book bundle from Hay Festival - terms and conditions below.
Our overall Hay Festival Book of the Year 2018 will be announced on the eve of Hay Festival Winter Weekend (22-25 November) and celebrated throughout.
