I would recommend this book both as entertaining and informative. Day talks about all the things readers might be puzzled about when first encountering Georgian/Regency-set novels - all the things Jane Austen left out because when she was writing, everybody knew them. What is special is that he then follows with short quotes about that particular topic from authors of that era. It would be a good book to give to someone new to Jane Austen, Georgette Heyer, et al. and the regency era.
