In the House of the Sacred Sisterhood, the unworthy live in fear of the Superior Sister& apos; s whip. In an atmosphere of constant threat and tense rivalry, they plot against each other and wait to see who will ascend to the level of the Enlightened - and who will suffer the next exemplary punishment. Risking her life, one of the unworthy keeps a diary in secret. Slowly, memories surface from a time before the world collapsed, before the Sacred Sisterhood became the only refuge. Then Lucía arrives. She, too, is unworthy - but she is different. And her presence brings a single spark of hope to a world of darkness.
