It's almost Halloween in 1992, as Fr. Jonathan Mears, chaplain at Indiana's famous Annandale Military Academy, looks into a report of cadets practicing so-called "magic" in Main Barracks. His investigation makes him witness of a very real ritual, one aimed directly at him and his family. Over the course of the following three years, repeated eldritch encounters drastically redirect the course of his own life and indirectly change even historic Annandale itself. A remarkable witch's brew of supernatural, Christian, classical ,and scientific arcana, concocted at an all-too-real midwestern prep school.

Annandale Military Academy’s summer camp at Walsingham College, Oxford, is no place for the supernatural: until a very persistent ghost shows otherwise. When two University of Chicago grad students and their uncle plan their honeymoon and his summer vacation in England, their family heritage draws them into a series of magical events beginning with visitations from a long-dead patron of the College and ending at the foot of Glastonbury Tor. In this sequel to Rough Magicke, Bishop Jonathan Mears and his family uncover not only the roots of their own craft but darker secrets as well.
