De Botton is more of a non-fiction writer, and I've heard that 'Essays in Love' is not a natural piece of writing. Never had the urge to check it out, but if you say you're unimpressed, I probably won't bother.
What do you mean by 'natural' piece of writing?
I'm only on page 30 or something so far though; maybe it'd get better.
And yeah, you're correct, the Peter Rabbit (et al) are the works of Potter.
Fair enough if you don't call them literature, but then, is there any such thing children's literature if this is the case?
