Jody McGrath's dolphin dreams are coming true! Her whole family is sailing around the world researching dolphins -- and Jody is recording all their exciting adventures in her Dolphin Diaries

The McGraths have arrived in Sundarbans Delta, at the mouth of the great Ganges River. There, Jody hopes to see the rare and unusual Irrawaddy dolphins. Her wish comes true when at last she spots one, whom she names Sandhi.

But her world is turned upside down when she learns there are poachers around, and Sandhi is missing. Does Sandhi have a secret hiding place, or has she been caught?
