Nothing like getting right down to the wire with Everything Austen II, is there? But sometimes you save some of the best for last.
You just have to love Margaret Sullivan (Mags) from the blog AustenBlog and her book The Jane Austen Handbook: A Sensible yet Elegant Guide to Her World, is one of my favorite Austen-related books. It really tells you everything you need to know about Austen's world in a witty way and if you know Austen well, you will certainly read some things that make you laugh out loud.
Some of my favorite parts are incidentals to the sections, such as "The Smell of the Shop" which Caroline Bingley most certainly tried to avoid - but we all know she's tainted. Additional sections include a variety of thing from how to have Christmas in the Country House to How to Dress (which taught me quite a bit).
To my mind, it is always more easy to learn and remember things when you are having fun and Mags does just that.
