»Five Go To Demon's Rocks
I read some of Enid Blyton's bucolic and context-free stories about young English lads and lasses getting into scrapes over their holidays: Five Go To Demon's Rocks.
Famously lampooned as idealistic, bland, and lacking any character-driven plot, the stories remain the best-selling children's books in the UK. They age well, perhaps because they have almost no setting other than the idealised British countryside.
