One does not simply walk into Mordor without a recap, so before we start our readthrough of Book IV of The Lord of the Rings, we’re reviewing previous chapters to reacquaint ourselves with a couple of characters we haven’t seen for a while (no one special; just Frodo and Sam, the guys whose mission really matters here). After a look back at the story so far, we look ahead to the themes we’ll explore in the coming season. But first, dragons rejoice! We welcome Jeremy Edmonds of the website Tolkien Collector’s Guide to the common room for a little Tolkien Collecting 101.
