The invocations

Five women are dead. The killer leaves no fingerprints, no DNA. Police are utterly stumped. In a world where only women can use magic and the men who know about it seek to eradicate them, three lonely teenage girls - one cursed, one hunted, one out for revenge - will team up to track down and take out a brutal supernatural killer. At the apartment of the fifth victim, Jude and Zara meet by chance, and there they find a clue that brings their paths crashing together: A strange business card bearing three words. Emer Byrne.
