She can touch an object and sense the emotions of the people who’ve held it before…

After solving the mystery of her predecessor’s death, geologist Petra Cloch wants to focus on her new job as the rocks and minerals curator at a quirky, small-town New Mexico museum. But her friend and colleague Liberty is suspicious of the “accidental” death of Frank Underwood, a retired petroleum engineer and rockhound who unexpectedly died while hiking. Frank acted odd and secretive in his last weeks—mumbling about an incredible find in the desert and aliens. Was he showing the first signs of dementia, or were more sinister forces at work?

Petra agrees to help excavate the truth, and soon, instead of meeting for book club, she and her friends become amateur investigators. Petra uses her gift and her brains to sort through the contradictory stories and confusing clues as she and her friends dig for answers.

Did Frank’s heirs decide to hasten their inheritance? Or did his rock shop business partner decide to go solo? Petra joins the local geological club to discover whether someone there acquired a taste for murder, because they’ll need rock solid evidence to catch a killer.
