It's senior year, and Maeve and her friends are practicing and strengthening their mystical powers, while Maeve's new relationship with Roe is exhilarating. But as Roe's rock-star dreams start to take shape, and Fiona and Lily make plans for faraway colleges, Maeve, who struggles in school, worries about life without them, will she be selling incense here in Kilbeg, Ireland, until she's fifty? Alarm bells sound for the coven when the Children of Brigid, a right-wing religious organization, quickly gains influence throughout the city, and when its charismatic front man starts visiting Maeve in her dreams. When Maeve's power starts to wane, the friends realize that all the local magic is being drained, or rather, stolen. With lines increasingly blurred between friend and foe, the supernatural and the psychological, Maeve and the others must band together to protect the place, and the people, they love.
