what on earth else is a book for???

Books are meant to be read, I'd suggest. So read them. I read many books without storylines, though most of them are non-fiction, but some are not. This is the old plot- versus character-driven stories debate. One of the reason I like so few mystery novels is because they are almost entirely plot. Many find plot-driven, linear narrative fiction to be the only kind of fiction worth reading. Some do not.

Ceci n'est pas un seing.
