Sam Hay grew up in Scotland in a family of bookworms. She always wanted to be a writer and filled endless notebooks with stories and poems. She trained as a journalist in Edinburgh and went on to work in newspapers for the BBC, before packing it in to move to Wales, have a baby and write her first children's book. Since then she's had more than twenty books published including the Undead Pets series about zombie animals and Screaming Sands, a ghostly trilogy set at the seaside. Kasia Dudziuk has been working as a designer and illustrator since graduating from the Falmouth University of Arts and has worked on books such as Barbie, Thomas the Tank Engine, Mr Men and Little Miss, Waybuloo and Winnie-the-Pooh. She lives in London.
