'Kamryn Vale is a Dahnan witch who wants nothing more than to complete her studies in the World Between and return to her normal life. But when a sister-witch is murdered and another kidnapped, Kamryn discovers a dark magic so terrifying it threatens the safety of both her worlds. Driven by the need to help in the investigation, Kamryn must deal with the complications of working with the mysterious Watchtower Knights.

'After two hundred years in exile, the Knights have been invited back to protect the Witches at the Collegium. They can’t afford any mistakes, and Alex knows his attraction for the fire witch has trouble written all over it. With one eye on the investigation and the other on Kamryn, Alex must balance his obligation to duty with the needs of his heart.'
