"Finding courage ... The day eight-year-old Hazel and her little sister, Bess, finally get a chance to start returning items to their spots in history, they run into a huge snag: their mother wants them to play with the kid next door. He's not only mean, he steals Bess's frog. Is Bess so upset she'll use the time machine by herself? When the girls went to their grandparents' mysterious farmhouse for the summer, they never dreamed they'd be spending their vacation trying to figure out a secret that leads them through time to meet historical figures and learn about their inventions, discoveries, and strengths of character that have helped shape history. In this third book, the girls travel to 1849 to meet Harriet Tubman on the Underground Railroad"--Page 4 of cover.
