From the back of the book:
The Flies Have It!
Leaderless and disorganized, the city of Westcrown reels after a terrifying incursion from the infernal realm. Yet while fiends stalked the streets, a more insidious rebellion unfolded below. Now a new power rises to lay claim to all of Westcrown! Only the insight of a crazed witch might aid the PCs in curtailing this dastardly coup. But can they hope to stand against the true masters of a city poised on the brink of ruin?
