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 pachers around, and Sandhi is missing. Does Sandhi have a secret hiding place, or has she been caught?
This is book #10 in this series about a family who rescues dolphins. My daughter enjoyed this series, though it was a little difficult for her 3rd grade reading level. I would recommend it for a reader who is older than her or for a challenging read for a child her age. It's a chapter book for older children.
