Ann Jungman was born in London, of German Jewish parents. She attended school in Hornsey and then went on to study law at university. Her decision to change careers and become a primary school teacher led her to become a writer for children. She began writing in 1982 and now has over 50 books to her name.

Ann writes for a wide age-range, from pre-school to early secondary, as well as for children with learning difficulties. She has also produced a history book series.

When he was younger Seb desperately wanted to discover a Lost World, but wasn't allowed out past tea-time, so spent his evenings making up stories instead.

He now lives in Bristol, England, where he runs an Animation company and works as a director, character designer, and illustrator. Seb also wrote and designed the almost famous Bertram Fiddle Adventure Games which are available on iOS, Xbox and Nintendo Switch.
