My son has listened to these over and over on Audible and we have them in print. They are his favourite books and are true classics. His two younger brothers have Yoto players and having Swallows and Amazons would.draw him in too! We'd love to have the full series of 12 books on Yoto but our favourites are:
Swallows and Amazons, Swallowdale, Peter Duck, Coot Club, The Big Six and We Didn't Mean to go to Sea.
