Anne of Green Gables
By Lucy Maud Montgomery

Well, of course you probably read it when you were a girl. Read it again. In Canada, it's almost an object of worship since the author is Canadian, but the truth is it's an absolutely wonderful book that will start you crying about halfway through, and you won't stop. I particularly love rereading children's books when I'm sick because I want guaranteed rapture; I want the book equivalent of mashed potatoes.
