Magick is real. And there is a secret world complete with its own agency, Veritas, to control those who would wield their power over "regulars", or threaten the secrecy that keeps them all safe from the persecution that nearly destroyed them.
For Cassie, a mixed blood witch, it's the only world she's ever known though she's never embraced her role as agent for Veritas. For Drew, a witch born to a non-magickal family, it answers so many of his questions. It is also the cause of so much loss and pain. And now, as he and Cassie attempt to find his missing brother, rumored to be working with a rogue witch and cult leader, it threatens to take the last of his family.
