Time and again, Emily--Em--Hansen uses her geological training and her unflinching scientist's eye to sniff out a killer. Now in her newest case, Em heads to Utah for a paleontology conference and ends up embroiled in murder when her host, a notorious dinosaur expert, ends up dead, stabbed with a dinosaur bone. The high-stakes world of dinosaur study and research, coupled with the secrets of a conservative sect of Mormonism, provide the suspects and Em, if she isn't buried like so many fossils by a determined killer, is forced to provide the solution.
