As the sole librarian of the Elijah County Library, the only dangerous adventures Reilly Cross encounters are contained in the books that she shuffles. However, all of that is about to change. While spending the week before Christmas with her estranged sisters at the Stoneyhill Inn in picturesque Grandville, Ohio, her world is suddenly turned upside down. The sisters are forced to confront old grudges; an old sweetheart turns up unexpectedly; and they find themselves drawn into the mysterious death of a beautiful young nun at the nearby boarding school of Winterstone. At the Icicle Ball, an annual social event at a local mansion, the sisters find themselves finally closing in on Sister Juliaas killer. But, as a snowstorm rages outside, will they be able to expose the real villain, in a shifting sea of ball gowns and tuxes, before Death pays another visit to Grandville?
