John and Antonia live in London. They are clean. They are tidy. They have firm ideas on how to behave.

Then they are sent to spend the holidays with their cousins at Roid House in the Scottish Highlands. Angus and Morag do not keep clean. They are not tidy, and they run wild. After initial horror on both sides, the cousins start to like each other, and they spend their time riding and sailing, and solving mysteries.

Joanna Cannan was an astute observer of children, and the reactions of the children to each other and the world about them are brilliantly observed.

First published in 1937, We Met Our Cousins is one of the earliest British pony books.
