Unseen

THE NEW YORK TIMES BESTSELLING AUTHOR

After Cassiel and Warden Luis Rocha rescue an adept child from a maniacal Djinn, they realize two things: the girl is already manifesting an incredible amount of power, and her kidnapping was not an isolated incident.

This Djinn — aided by her devoted followers — is capturing children all over the world, and indoctrinating them so she can use their strenth for herself. With no other options, Cassiel infiltrates the Djinn's organization — because if Cassiel cannot stop the Djinn's apocalyptic designs, all of humanity may be destroyed.
