A shipment of dinosaur bones meant for a new exhibit has been stolen from the Capitol City Natural History Museum! But even worse, the group of paleontologists working on the shipment has disappeared too - and among them is Wilson Kipper's mother. Wilson and his friends are determined to get to the bottom of the mystery, but can they do it in time to save his missing mom? Discussion questions, writing prompts, a glossary, and nonfiction resources continue the reader's learning experience long after this ebook ends.
