The Mystery at Dolphin Cove

One dolphin darling! Two bottlenoses breaching! Three dejected dolphins! Four wet kids! And lots of click and whistles! 

Avery, Ella, and Evan love dolphins! So when they get invited to see them up close and personal, they jump at the chance – just like their new dolphin pals Marco and Polo! But when dolphins start disappearing all along the coast, the kids are determined to find out what– or who–is the culprit! "We're got to save the dolphins!" 

Clever clues lead the kids on a wet and wild adventure full of science, high-tech gear, and LOTS of fun. Take a dive into this mystery, and you’ll be hooked!
