In the seventh mystery to feature Temperance Tempe Brennan, the forensic anthopologist is summoned from North Carolina to her other jurisdiction, frigid Montreal, to testify at a court case. Once there, she is asked to investigate a recent discovery in a pizza parlor basement. Tempe eventually uncovers the skeletons of three teenage girls, apparently murdered sometime in the 1980s, and is determined to find their killer, despite the unhelpful attitude of the Montreal police. Bestselling author Kathy Reichs informs her fiction with her own expertise and experiences as a forensic anthropologist for North Carolina and Montreal.
