Jan and Sara were already friends when one day they decided they wanted to write children's stories and it would be more fun to write them together. That was 18 years ago. Since then they've written over 160 stories - including some about ghosts, football, ghosts playing football and naughty gargoylz. Jan lives in Essex with her family and Sara lives in London with hers. They both have black cats who completely rule their lives.
