This is by far Reichs’ most intriguing work in her series that features Dr Temperance Brennan, anthropologist. In this latest novel, Dr Brennan sets about to uncover the identity of a young girl’s remains, from a region familiar to her and her best friend, who’d mysteriously disappeared years ago. We also see more of her sister, who is just about the opposite of Tempe, being frivolous, flamboyant and decidedly rash. The story is about 6 missing girls and an investigation which introduces us to the world of child pornography. Quite grotesque, really, but the ending is one of Reichs’ best, as there is such a delightful twist and an interesting insight into human nature.
