Far Distant Oxus

A group of children heads off on their own for a series of adventures.

It sounds a lot like some of the most popular English children's books of the first half of the 1900's, doesn't it?

One of the novelties of this book is that the authors themselves were teens when they wrote the book.

The children travel on horseback around the moors of England (and, later, aboard a raft down the river to the sea) without adult supervision. It's that lack of adult supervision that might seem most shocking to contemporary readers.
