I loved stories about horses and ponies,
Norman Thelwell, Marguerite Henry, C.W. Anderson were favorite authors, along with many more.I liked the Danny Dunn series (science-based adventures), Nancy Drew series for a while (amateur sleuth mysteries), but quickly grew bored of the formula plots and never finished the series though my mother kept buying them. I also liked Trixie Beldon and The Hardy Boys. All of Beverly Cleary's books (favorite was Runaway Ralph !),
I didn't much care for the Dr. Seuss books. While I see, today, they are fun, when I was a young reader, they seemed like nonsense and I preferred an engrossing story to silly rhymes.
