In 16th century England, Isabella Launder little realizes the twists and turns her life is about to take as she surrenders herself to a small nunnery in order to forget her unrequited love of the courtier Thomas Giffard. She must learn–along with her sisters in Christ–the true nature of faith and survival, withstanding passionate jealousies, intrigues, and the emerging threats to the Church itself as one by one the monasteries are dissolved. Inspired by the true lives of Isabella Launder and Thomas Giffard and set amid the onrushing storm of Henry VIII's break with Rome, obsession opposes faith in this tale of a wealthy knight and the last prioress of Blackladies convent.
