From the publishers blurb:
After being spurned by a handsome noble, the warlock Zor Zaynne placed an infertility curse upon a region of the land. Although she accepted numerous payments from noble families to reverse the affliction, she never intended to allow any family to reproduce. After years had passed, rumors of the warlock’s death became popular. Recently, an acolyte of a local order uncovered a potential reversal ritual. All it requires is the warlock’s organs, but they are hidden deep within her treacherous tomb. Nobles have offered the reward of any treasure found in the lair if the organs can be retrieved. Many have already tried, and all have failed.
