Tem muita coisa legal na Livraria Cultura. Alguns desses livros valem super a pena. ^^
Só uma coisa: a mairia dos livros aí são sobre Tolkien, não dele em parceria com alguém. Até onde eu sei, ele nunca chegou a concluir nenhum livro de ficção em parceria (se eu não me engano, chegou e ter um projeto com o Lewis, que nunca foi pra frente.)
