I really enjoyed this one. Although it is set in the time of Henry VIII (one of my favourite settings for novels) it is not a historical novel per se; it does not focus much on the actual history of the period, but more on the plot which revolves around the search for a mysterious relic said to have enormous power. But there is also a very human element to the novel; the protagonist, Sister Joanna, is a novice nun, who has an array of experiences beyond that of most nuns of the period - a stint in the infamous Tower of London, witness to the torture of her father and the burning of her cousin, an unlikely alliance with two friars, and even a taste of rather worldly, yet chaste, love.
Imagine if Dan Brown and Victoria Holt collaborated to make a novel and consulted Philippa Gregory on the historical issues, and you may have some idea of what this book has in store for you. The historical element is there - during the course of the story we meet Thomas Howard, Catherine Howard, Katherine of Aragon, Henry VIII, Bishop Gardiner, Princess Mary, Anne and George Boleyn, and we visit the Tower of London and the apartments of both Katherine of Aragon and Anne Boleyn, and the novel is set during the period of the dissolution of the abbeys and monasteries, so the historical background is undeniably there. However, it is just that - the background. It provides the setting for the story rather than being the story itself. The mystical element is there too (hence my Dan Brown reference) - various characters in the story are searching for a relic that supposedly imbues its possessor with a certain power, and there is a race to be the first to lay hands on it. And then there is the human element of love, fear and a range of emotions, a coming of age for the protagonist and an air of suspense that one might be familiar with from the works of Victoria Holt.
All in all, this is a fast paced read and one that I would have no hesitation in recommending.
