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 and is a graduate of the Golden Egg Academy and a member of SCBWI. She lives in Essex with her husband, two bookworms and two rabbits.

Jenny Taylor is an illustrator and graphic designer originally from Scotland, but now living in Preston, England. Drawing stories since 1997, when she first discovered what pencils and paints could really do, she has finally achieved her childhood dream with this debut book about aliens and jam. When not drawing, Jenny enjoys long walks in the shade with her ginger companion, "attempting" new and complicated recipes or watching her favourite animated movies.
