Sibéal Pounder is the author of two much-loved and seriously stylish children's fiction series, Witch Wars and Bad Mermaids. Before becoming a full-time writer, she worked for the Financial Times where she researched the How To Spend It section and wrote the For Goodness' Sake column. Her first book, Witch Wars, was shortlisted for the Waterstones Children's Book Prize and the Sainsbury's Children's Book Award and she was also a World Book Day author for 2019. Her latest book, Tinsel, is a funny feminist play on the tropes of Christmas and was extremely well-received by booksellers and readers alike. Sarah Warburton – a super-talented, super-illustrator superhero – works in a studio at the bottom of her garden. She lives in Bristol in a homely hideaway.
