The Godivas Go Riding

This book was released by Dr. Seuss.
It is a sequel to the obscure book The Seven Lady Godivas.
It takes place after the events of the original book with The Godiva sisters being happily married to The Peeping Brothers and living in individual castles. While they are happy with living marriage lives, they began missing being in each other's company.
They get together for a family reunion and decided to go on an adventure. 
They leave England and travel on a horse and they go into a forest with trees and animals. They also do fun activities like swimming (in their birthday suits since they're nudists), hiking, climbing, yoga, eating fruits and vegetables, and drinking tea.
After that, they discuss their marriage lives with The Peeping Brothers and their mother Lady Godiva herself.
Once it was time to leave the forest, they travel on the horse back to England and they visit the castle that they lived in when their father Lord Godiva was alive and before their marriages to The Peeping Brothers.
After that, they all leave the castle, say their farewells and go back to their individual castles with The Peeping Brothers. It ends with them discussing the adventure that they had to their respective husbands.
