Chrissie Sains grew up in Billericay, Essex, where she spent her childhood seeking adventure and finding trouble. Described by her teachers as having a “lively imagination”, Chrissie's escapades include her attempted rescue of the school's pet fish and the discovery of a dead body in a field that turned out to be two tyres under a sheet. She has swum with sharks, scuba-dived shipwrecks and sky-dived from a plane. Chrissie has a background in marketing and events but now writes full time. She is the author of the Jam Factory series and the co-author of I Got This, with Cara Mailey. She lives in Essex with her husband, two bookworms and two rabbits.Nia Tudor is a Carnegie Medal and Klaus Flugge long-listed children’s illustrator living and working along the Welsh coast in South Wales, UK.
