"Māra is loose. His kin walk among us. You must find them- before it is too late." There is one cardinal rule that all users of magic abide by: that the human world must remain ignorant of the practice of magic. So, when they discover that the demon king Māra has been set loose - raising spirits, upending graves and seeding chaos in the human world - it's up to Shalini and Kai to find him. But the search brings with them shocking secrets that could unravel everything they ever knew about magic.
