"D.A. is more of a researcher than a storyteller, so she's naturally nervous when her parents sign her up to speak in front of a sellout crowd. But thanks to the Friz, D.A. gains inspiration from the greatest storytellers on Earth: glaciers! These mighty, frozen time machines guide the class through the Earth's last 10,000 years, and the . . . tale of the changes it has witnessed"--Amazon.
