Chaucer is a really interesting author. I studied 'The Miller's Tale' in A-level English (aged 17 / 18), and loved the bawdy X-rated story that was smuggled in via weird medieval English.
For a different perspective on another of Chaucer's characters, I also recommend 'Chaucer's Knight', by Terry Jones of Monty Python fame. The book is a bit controversial, but it's fascinating to see what appears to be a tale of courtly chivalry analysed by a modern satirist. Jones suggests that the Knight is really a blood-thirsty mercenary associated with multiple historical massacres, and points out where Chaucer is being satirically critical rather than simply praising the Knight.
