Orphaned Beluga

They get to travel on a research boat and meet the St. Lawrence River belugas face-to-smiling-face! Then they hear about an orphaned beluga in trouble. A dam is being built across the small river he is living in. Can they help the researchers save the young beluga before he's trapped there, alone, forever?"--Back cover.
