The Coven is reunited - but broken. Niamh is back from the dead, but she hasn't come back alone. Elle mourns a son she never had. Ciara languishes in a prison for witches. And Leonie reels from a very unexpected surprise. Four very different witches with one thing in common: they were unwittingly chosen by the dangerously charming Lucifer, the demon king of desire, to fulfil a dark prophecy.
