Margaret is a Princess of England whose father was exiled. She, her sister, and brother were raised in Hungary with a Hungarian-Russian noblewoman for a mother. When their father returns to England to claim the crown when their uncle dies, he drops dead only a week after they've returned. Margaret is sure that she killed him, having encouraged him to eat some almond sweetmeats. The family flees from William the Conqueror, who has "stolen" the crown, Edgar's (Margaret's brother) by rights. They are shipwrecked, washing up in Scotland.
Margaret and her sister were educated in an abbey in France, and Margaret's wish is to become a nun, dedicating her life to contemplation and learning. But this is not in her future, as Margaret herself is the bargaining chip for aid from the Scottish king, Malcolm -- of Shakespearean fame for killing MacBeth, the "evil" king. MacBeth's widow, Lady Gruadh, still has followers in the shire of Moray, in the Scottish highlands. As surety for her good behavior, Malcolm takes Gruadh's granddaughter, Eva, as hostage. Eva has trained as a Scottish bard, a harpist/poet/entertainer normally accorded great respect in the highland society (and Irish).
Eva and Margaret become friends, which puts Eva in quite a quandary, as her grandmother, Gruadh, has tasked her with spying on the Scottish court, and in stealing a manuscript that paints MacBeth as evil. (Of course, b/c the victors write history!) But Eva cannot help but become friends with the saintly Margaret, who goes to chapel multiple times per day and often fasts -- to anorexia, IMHO. Eva becomes more involved in Margaret's life - and a few shenanigans - as Margaret will actually bend the rules in feeding the poor and releasing prisoners around the castle!
In the denouement (and also the prologue), Eva has gone too far, caught in her theft of part of the manuscript and attempting to meet with her grandmother. Will Margaret defend her friend, or let Malcolm burn her as a witch?
I really enjoyed this novel about Saint Margaret of Scotland (yes, she was sainted after her death). According to the author notes, there is apparently a lot of source material, unusual for a medieval queen, simply because she WAS sainted, and her confessor wrote a biography of her only a few years after her death. So the major escapades told in the story are actually based on fact!
I only rated the novel 4 stars, however, b/c one can only read so many times about how many times a day Margaret prayed; how often she was begged to eat something (even during her pregnancies) instead of feeding her own food to the poor from her own bowl; or how many skirmishes Malcolm and Edgar perpetrated against the Normans in northern England.
