This is the 15th book in the Temperance Brennan series by Kathy Reichs, and as usual a fascinating mystery. Had I not read the previous 14 books by Reichs, I may have scored her latest mystery "Bones are Forever" at a 4 rather than a 3 - but the story simply lacked the complex forensics and character interactions of previous books. However, great plot as usual! Forensic anthropologist Temperance "Tempe" Brennan is back at work in Quebec when she is asked to the apartment of a missing woman, Amy Roberts, who may have recently given birth. Tempe makes a ghastly discovery, first finding the body of one deceased infant, and then 2 more bodies in the run-down dwelling of the missing woman. Of course, homicide detective Andrew Ryan, Tempe's ex love interest, is leading the investigation, and there is nothing but tension between the pair throughout this story. Indications are that the mysterious Amy Roberts may be a prostitute, and in searching for her Tempe and Ryan are joined by Canadia Mounted Policeman Ollie Hastings, another one of Tempe's past love interests. This creates additional tension between the trio. The trail for the missing woman ends in Yellowknife, a remote city in Canada's Northwest Territories. As in Reich's previous novels, the plot thickens, becoming more complex as the story progresses. Between infanticide, environmentalists, prostitution, diamond mining, and a missing dog, this story has it all. Warning for fans of the series "Bones" who have not read any of Reichs books - these are far darker than the tv series, with more complexities to the characters and without a humorous supporting cast of characters to take the edge off of some of the grisly deaths and forensics. Still, A forensic anthropologist herself, Reichs knows how to weave a detailed and engaging story.
