Mary Tudor has received a rather unfairly negative reputation in history. Hilda Lewis's book is a complex and compassionate glimpse into the psyche of Henry VIII's eldest daughter-- a woman who loved her mother enough to defy the father who could strip her of everything, who both loved and feared her younger, more charismatic sister, and wanted nothing more than to preserve her faith.
By way of criticism, I would say that perhaps this novel might be a bit generous to Mary. Anne Boleyn's famous plea for Mary's forgiveness on the eve of her death, I imagine being met with a less forgiving attitude. And although Mary states at one point that many believes burning a heretic ultimately saves their soul, well, I'm not certain generous motives can be ascribed to *everything* Mary did. That said, though, this book is a nice counterpoint to those who would write her off as a tyrant.
There were very moving moments throughout this novel, and Lewis does a wonderful job of capturing Mary sympathetically, while still portraying Elizabeth and Mary's rivals in a kind light. I look forward to reading more by this author.
