It's even grimmer than you'd expect.
Judging by your reading history, I think you really need to read a book about kittens and puppies and lambs.
I haven't been in a kitten, puppy, lamb space even once in my life. I was super-stoked to read Rabbit Hill in 4th Grade because I thought it was Watership Down, a book my parents read aloud to me in Kindergarten.Rabbit Hill is not Watership Down.
Rabbit Hill is not Watership Down.
George Orwell is depressing. He could have used a bit of lamb space himself.
Down and Out in Paris and London is somewhat upbeat in parts, at least.
