Big things are happening for Maeve and her tight-knit coven in Kilbeg, Ireland. Fiona lands a role on a TV show, Roe's band is poised to hit the big time, and Lily has a new punk style and passion for tattooing. Then there's Maeve, whose magic is growing stronger and more frightening. She finds herself increasingly lashing out, doing and saying cruel things without knowing why. When her recurring dreams begin to involve her physically manifesting in other places, Maeve realizes the power she wields might not be entirely under her control. She turns to enemy-turned-maybe-friend Aaron for help, which means pushing her other friends away. But when the two learn that the religious cult the Children of Brigid is kidnapping vulnerable teenagers in preparation for a dangerous ritual, Maeve must risk letting an older magic consume her. She'll need all the protection--and love--she can get from her scattered coven.
