Leaving the Shallows — Ben M. Baglio

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.

After weeks at sea, Jody and her family have arrived at Hervey Bay, off the coast of Australia. There, Jody befriends a gorgeous pink-and-white dolphin named Dawn.

Jody notices a neighboring tourist operation isn't keeping the dolphins' interests in mind and, as a result, Dawn becomes ill.

Will Jody be able to convince them to change their ways before it's too late?
