Dr. Roberta Ray of Montana Tech's Liberal Studies Department will be doing a book signing for her recently released Angels on a School Bus at Books and Books (206 West Park St.) on Saturday, September 17th from 2-4 PM. The book tells the story of the Camp Husky dog rescue in Butte and how the dogs adopted during the rescue affected the lives of those who adopted them. Many Tech alumni, faculty, staff and students are featured in the book. Net proceeds from the book will be donated to animal help organizations such as Butte’s Spay-Neuter Task Force.
