From World Fantasy Award-winning author K.J. Parker comes a fiendishly complex tale of ecclesiastical espionage and divine deceptions. When the Church of the Invincible Sun is looking for someone to do its dirty work, they call on Sister Svangerd and her priest. Stealing a book might sound like a relatively simple task, but this isn't any old book. To get their hands on it, they must impersonate a legendary figure, create the world's most expensive letter of introduction, and sneak into the most heavily guarded library in the world. All in a day's work, but the machinations of the mysterious Loyal Opposition threaten to derail their best-laid plans. And when Svangerd begins to act not at all like herself, it soon becomes clear that the secret war between divine forces is going to test everyone's faith.
