Stella Familiar was created by the London Coven to protect the city from the monsters that lurk in the shadows. She's fought against the darkness for decades, but now something new has come to town. Something that's torn her world apart. This monster did the impossible: it murdered the three most powerful witches in London, putting the city in peril, and leaving Stella alone for the first time to fight back against a power she doesn't understand. An evil beyond anything she can imagine is loose; something with the power to crush her like a bug... and it's back to finish what it started. Does Stella have what it takes to defeat a threat this powerful, or will the creature of her nightmares snuff out the Coven for good?
