Muir, Helen

Helen Muir was born in Wirral, Cheshire, and worked as a reporter on a local newspaper before she became a fulltime writer. Dan's Secret Pony is, as far as I know, the only pony book she has written, though she has written several other novels for both children and adults.

Finding the book
Dan’s Secret Pony is reasonably easy to find, and shouldn’t be too expensive.
