Hmm good question!
Off the top of my head - "Manka the Sky Gypsy", by 'BB'. A somewhat cheesy name, but an amazingly evocative description of the extensive North Norfolk saltmarshes and their Pink Footed Geese. Loved it as a youth, really his books are good for all ages, in the beautiful way he describes the countryside. The author was an artist, and his books are just like paintings. 🙂🐦
