Author bio
Sibéal Pounder writes the kind of children's fantasy that feels busy, funny, and a little gloriously unhinged. Her books are packed with secret worlds, sharp jokes, odd rules, and kids who are braver than they first look. Even when the plots go wild, the feelings underneath are easy to recognize.
She has Irish roots, grew up in Scotland, and spent a big part of her childhood in Dublin with her family. Dublin matters a lot in her imagination. She has talked about Sandymount, her grandparents' house, and the funny people around her there as lasting influences, and that mix of city energy and family memory turns up again and again in her fiction.
Before she published novels, Pounder studied History at St Andrews, Publishing at City, and later took the Faber Academy's Writing for Children course. She also studied Quentin Tarantino films at Yale. Her working life started in journalism and features, including research and writing for the Financial Times, as well as work for Vogue online, The Guardian, and fashion trend forecaster WGSN.
That background helps explain part of her style. She notices clothes, surfaces, and social absurdity the way a good features writer does, but she also knows how to keep a story moving. After years of writing about real people and real-world culture, she turned that eye toward children's fantasy and made her debut with Witch Wars.
The city beneath the sink pipes was inspired by Dublin.
Witch Wars introduced Tiga Whicabim and a witch world full of riddles, glamour, and black-and-white chaos. The book was shortlisted for the Waterstones Children's Book Prize and the Sainsbury's Children's Book Award, but readers mostly seem to come back for its pace, silliness, and warmth. Pounder followed it with the Bad Mermaids books, which swap broomsticks for crabagrams, shell cities, and a very chatty seahorse, then later with Neon's Secret Universe, where unicorns turn out not to be horse-shaped at all.
She likes taking familiar magical creatures and asking what if we had the story wrong.
That habit gives her books a clear signature. Witches live under sink pipes. Mermaids worry about fashion and transport. Unicorns use goo-powered magic and hide in plain sight. Even Tinsel, her Christmas adventure, starts by nudging a well-known myth sideways and wondering whether history forgot the girls. Readers who like her work usually mention the same things: the jokes, the speed, the weird detail, and the fact that her heroes are rarely neat or polished. They panic, argue, improvise, and keep going.
Pounder has also written beyond her own series. Beyond Platform 13 takes readers back to Eva Ibbotson's magical world, a place she loved as a child, and puts Odge Gribble at the center of a fresh rescue mission. She also adapted Wonka into prose, which suits a writer who clearly enjoys elaborate worlds, eccentric rules, and sugary spectacle.
She lives in London and has said she still tries to get back to Dublin whenever she can. That combination, London life, Irish family roots, and a very lively imagination, helps explain why her books feel both contemporary and completely off their heads.
