Those whom God wishes to destroy he first makes mad...
The convent of Our Lady of Mercy stands alone in an uninhabited part of the Spanish sierra. Its inhabitants are devoted to God, to solitude & silence; six women cut off from the world they've chosen to leave behind.
Everything changes on the day that Mother Superior Maria Ines discovers a suitcase punctured with air-holes at the entrance to the retreat. Soon she is to find the box & its contents are to have consequences beyond her imagining, & that even in her carefully protected sanctuary she is unable to keep the world, or her past, at bay.
