Fiona Satow wrote three children’s Christian stories. One, My Friend Krow is unusual in that it includes Fell ponies - not, by a long way, the most frequent native breed to find in a pony book.
Finding the book: reasonably easy to find.

Nick and his sister run wild on the hills, and life seems wonderful until in a tragic accident, Nick’s sister dies. And Nick was responsible. Nick’s terrible guilt threatens to overwhelm him until he is given a lifeline in the shape of the local Fell ponies, which he helps to train.
