This is an extremely useful book and so nice having all the monarchs in the one book, with a short chapter for each monarch. It has 6 very helpful genealogical tables, Normans & Angevins, Plantagenets, Houses of Lancaster & York, Tudors & Stuarts, House of Hanover, Houses of Saxe-oburg-Gotha & Windsor. I keep this book beside me whilst reading other books from these periods and it is a great help for cross-reference purposes. It is also very interesting as are all Antonia Fraser's books. Highly recommended.
