After the tragic death of the friend he secretly loved, he's ruthlessly suppressed any desire for another man. So when handsome ex-Pinkerton Griffin Flaherty approaches him to translate a mysterious book, Whyborne wants to finish the job and get rid of the detective as quickly as possible.

But the powerful cult that murdered Glenn has taken root in Widdershins, and only the spells in the book can stop them.
