There aren't many children's classics I didn't read when I was a kid. I loved to read and I read very quickly. My parents bought a set of encyclopedias and I read them cover to cover. I read my school textbooks cover to cover near the beginning of the school year, then when I was assigned to read parts of them thoughout the school year, it was just a review for me. I read my dad's old textbooks, which he kept. I read friend's books and library books.
I guess of the children's classics authors, I very much liked Frances Hodgson Burnett, Lucy Maud Montgomery, Jane Austen and Charlotte and Emily Bronte. I also liked Leo Tolstoy, J. R. R. Tolkien, C. S Lewis, and Edgar Allan Poe.
