Mysterious claimings, kidnappings, and disasters are occurring the world over. Sara McKay knows that can only mean one thing—the fata, magical beings from the planet Hecate intent on ruling Earth, are growing stronger. With the help of their pneumas, benevolent fata souls residing inside Sara and her sisters Lily and Evelyn, the McKay witches of Ireland prepare for war. However, with Sara no longer playing peacekeeper between Lily and Evelyn, strong insecurities stemming from Sara's past make a reappearance in her life. Once the most powerful triplet, she struggles to master the lifesaving skills the pneumas introduce and fully integrate with the supernatural soldiers flocking to Fern Cottage. Will Sara's instability help Noro and King Dimia drive a wedge between the triplets the fata forces can exploit? Or will Sara's issues be just the thing the Triplet Army needs to win an otherworldly war?
