Erin Hunter is actually three people! She is experienced children's book writers Kate Cary, Cherith Baldry and Victoria Holmes who all live in the UK. Vicky comes up with the story ideas and makes sure the books stay consistent and Kate and Cherith take it in turns to write the books. They came up with the single name, Erin Hunter, to avoid confusing their readers by having books from the same series in different places on the bookshelf.
