The Devil's Prayer by Luke Gracias in Paperback

In Spain, a nun's public suicide shocks thousands. For Siobhan Russo in Australia, it is a revelation: this nun is her long-lost mother, Denise, who vanished years before. Seeking answers, Siobhan journeys to the isolated convent where her mother once lived. There she uncovers Denise's final confession, a book detailing a horrific betrayal that left her mute and crippled, and reveals her deal with the Devil for revenge. But in this desperate bargain, Denise also wagered Siobhan's soul. With her enemies now aware of her possession of The Devil's Prayer, can Siobhan escape the extremist monks determined to reclaim it and prevent the unleashing of apocalyptic horrors upon the world?
