Dolphin Song by Lauren St. John

Just as Martine is settling into life at Sawubona, the wildlife game reserve, with her grandmother and Jemmy, her white giraffe, she must leave for two weeks on a school trip off the coast of South Africa. What begins as an exciting sea adventure quickly turns perilous when Martine and five of her classmates are thrown overboard into shark-infested waters. They are saved by a pod of dolphins only to end up marooned on a deserted island. The castaways, at odds with one another, must figure out not only how to survive, but how to save the dolphins that have mysteriously beached themselves on the island's shore. What do you think Martine and her friends will do? Will they get help? Or will they stay there, alone, stranded?
