This book is the tale of when the Five get separated into boys and
girls. George and Anne have to go to a Riding
School while
the boys are at home. The boys come to meet the girls at the
Riding School and they stay there. While they are at the riding school, the five meet Henry (short for Henrietta) who is a very enthusiastic and skilled rider. George gets jealous of Henry and they become enemies calling each other by their first names which they totally despise. I like the bit when they find the crashed steam engine and they search for the track. The rating I would give this book is 8/10.
