In churches and convents and other religious communities, sisterhood takes many forms, forged and tested by such mundane threats as disease and despair, but also by terrors both spiritual and existential—Satan's subtle minions and the cosmic nightmare of the Cthulhu Mythos. Sisterhood: Dark Tales and Secret Histories presents sixteen horror stories by some of the genre's leading female voices. Their settings range around the globe and across the centuries, from 6th century Ireland to 17th century Virginia to Indonesia in the recent past.
