Jo Cotterill has been an actor, a teacher and a fireworks technician, but she likes writing best. She has published over forty books for children and young adults, including the critically-acclaimed novels Looking at the Stars and A Library of Lemons and Jelly. She writes short books for readers who struggle, helped by her previous experience as a learning support assistant. Jo writes the superhero part-book, part-comic series Electrigirl with illustrator Cathy Brett. When she's not reading, writing or out visiting schools and festivals, Jo likes to write songs and make interesting things out of paper. She lives in Oxfordshire with her family.
