The Crown by Nancy Bilyeau

 This was a good, historical fiction, mystery.  It took place during the reign of King Henry the 8th and involves the plight of those of the Catholic faith at that time. A devout young girl leaves her priory to offer support for her beloved cousin, who is about to be burned as an enemy of the realm.  Because of her attempt to comfort her, she is thrown into the tower.  She encounters a rather ruthless Bishop, who bargains for her and her father's lives, by having her find the ancient Athelstan crown which is believed to be hidden in her priory. She then finds herself entwined in finding the crown, a murder, and a lot more mysteries.  The plot is very involved, but the struggle of those suffering for their faith is moving.
