This is an interesting text, looking at Chaucer and the world he inhabited in 1386. It is by no means exhaustive - though how much can/will we ever know, 600+ years on? The author sets the scenes nicely, almost too nicely with plenty if addition information about the people moving around Chaucer at the time. You could argue it was too much 'other' information, not directly tied to Chaucer himself, but much of it set up important events to come. And with this volume itself being roughly only 255 pages, it's not as though it was a burden.
While you may not learn anything new from this one if you're already well-versed in the life of Chaucer, it's still an interesting read - in fact I read it in just an afternoon. Recommended for those interested in both the time period and the man himself.
