Saskia Gwinn

Saskia Gwinn is an author of children's books. She has worked in children's publishing for nearly 20 years, crafting best-selling, award-winning non-fiction books to inspire kids on almost everything from how time began to the silliest things in the world today. She lives in Hertfordshire with her two boys who hope dinosaurs will one day revisit Earth. 

Her first picture book, I Am NOT the Easter Bunny!, was published by Simon & Schuster in 2023. Her more recent picture books include Next Door There is a Dinosaur (Bloomsbury, 2026) and Who Said Poo? (Farshore, 2026). 

She writes non-fiction on all sorts of topics – from animals to space, and dinosaurs to the human body. Some of her most recent non-fiction books include Theia: The Little Planet Who Made the Seasons (Post Wave), Into the Dark: Adventures of Nighttime Animals (Farshore), What a Bottom! (Hachette), Secret Stories of Space (Wide Eyed Editions), and I See a Dinosaur and I See a Tree in the Teeny Tiny Science series (Nosy Crow in collaboration with Cambridge University).
