Margaret the Queen — Nigel Tranter

First she was Margaret the refugee. A Saxon princess, sister of Edgar
Atheling who, but for William the Conqueror, would have been King of
England. She came to Scotland in 1069.

Beautiful, sympathetic and devout, she was an unlikely consort to the
rough and ready Malcolm King of Scots and slayer of MacBeth, a man who
cared for little other than hunting, drinking and the brutal arts of
war.

Yet, through her gentle strength of character and intelligence, she was
to have a profound and lasting effect on her adopted nation and people
that lasts to this day.
