Sophie grew up in Chelmsford, Essex. She failed the 11+, had a weekend job at a boarding kennels where she suffered workplace bullying from a goat, and nurtured a dream to have a career she could do in her pyjamas. She worked at two London publishers before finally achieving her ambition by going freelance in 2003.
She entered Mumsnet’s first Bedtime Story competition in 2012 and Michael Rosen picked out as a winner her story about a pig-riding sheriff. Since then she has been writing offbeat and funny stories for 8-12-year-olds. She lives on the edge of south-east London with her family.
