The Advent of the Yule Queen (The Thamauturge of Annandale Book 3)

Sometimes being a cadet at a military academy sucks. Even if you're the highest-ranking person in your class, even if the school's a family tradition, and even if your great-uncle is the local bishop and president of the school's board. Even, for that matter, if you spend family vacations sharpening your magic skills. It's 2017, Wills Evans is not getting off to a good start in his Second Class year at Annandale Military Academy, and Bishop Jonathan Mears suspects that some of his great-nephew's problems may stem from an external, and supernatural, source. Finding it is another question.
