After successfully apprehending a map thief at the beginning of summer, Dev is going to spend the second half of her summer vacation in Montana with her best friend, Katie, exploring the outdoors and NOT getting into trouble. But after participating in a dinosaur dig, Katie and Dev suspect that someone bad is in the Badlands when Katie's found fossils are switched out for old rocks. The good news? With Mom back in New York, no one can stop Devlin from investigating! But the fossil thief isn't the only danger here, as snakes, scorpions, and bears abound, making Montana a treacherous place for finding answers. And when the mystery takes Dev and Katie back to Manhattan--to the Museum of Natural History--the case gets even more complicated, even with Dev's friend Booker there to help. Dev has to use her brains, brawn, and yes, okay, the lessons learned from her police commissioner mother if she wants to dig up the truth once and for all. The book is complete and in FINE or better condition with some overall light wear. There is a small black dot on the bottom edge of the closed book pages. The author, Linda Fairstein, has flat signed her name on the half-title page. (see pictures)
