If, like me, most historical narratives are a bit hard going (all those dates and wars!) then this is a perfect antidote: Fraser focuses on the personal lives of Henry and his wives, relegating the politics to the background.
She manages to keep all the wives distinct and give them their own persoanlity which is excellent, as well as charting Henry's development from 'angelic' young king, to bloated monster (her words, not mine).
My only slight quibble was the pacing, since we lost some sense of time between Catherine of Aragorn's long marriage and the shorter interludes that followed, but that really was minor. The end after the death of Henry felt unnecessary too, but that's personal taste.
Where Fraser really excels is in taking the sterotypes and school-kid images of the wives and revealing the 'truth' (or one truth) behind them. She keeps a balance too, never siding with one wife over another.
Altogether an excellent read with a fine sense of period.
