Sarah Dixon lives in York with her husband and their two children. Her love of sci-fi began watching Dr Who battle the Daleks. She now keeps a TARDIS key with her at all times, just in case! After years of reading and watching sci-fi, her brain was so full of story ideas and memories of things her children had said or done that Alfie Slider vs the Shape Shifter came pouring out of her fingertips. Sarah aims to write books that adults will enjoy reading to children as much as children enjoy reading themselves. Stories to bring families together, packed with action, adventure and a side order of humour. Sarah's world(s) don't only revolve around Alfie Slider, and she also creates short stories for all ages. She has been included in a number of anthologies, has won an award for a ghost story and is a member of writing group York Writers. When she isn't writing Sarah can probably be found visiting a school somewhere, encouraging children to read, write or save the world!
