Sam Caldwell has illustrated Monster Diaries: The Minotaur and the Greatest Escape Ever, the second book in Anne Miller's hilarious illustrated series published by HarperCollins Children's Books. Following the success of The Cyclops and the Worst Party Ever (April 2026), this new instalment gives the Minotaur his own voice, retelling the Greek myth from the monster's perspective for readers aged 7 and up. Praised by The Telegraph for its "anarchic" energy and "immersive illustrations", the series is one to watch.
