Dario and his mother travel from Brazil to Cape Cod each spring so that she can work. Atlantic right whales travel up to Cape Cod early each spring in search of food. This book is about the friendship between Dario and a young right whale. They notice each other at the beach and strike up an unlikely, but sweet relationship. When Dario whistles, the whale spouts. When Dario waves, the whale breaches. Their friendship lasts through the spring. One day, Dario cannot go to the beach, because he has a cold. When he returns to the beach the whale seems to be gone. A young girl tells him that the whales migrate in May and that they are gone. Dario is upset, but jumps up to see his friend just offshore. He enters the water and the whale comes closer than it ever has before. They exchange greetings (whistle/spout, wave/breach) and when Dario asks the whale if he has to go, the whale blinks his large eye. Dario asks if he will return and the whale slaps the water with his huge tail in response. And, Dario knows that the friends will reunite next year.

Portuguese words are scattered throughout this story of two migrants that form a beautiful and enduring friendship. Information about Atlantic right whales at the end of the book will give students solid facts about these mammals. This is a very sweet story with lovely pictures that students will thoroughly enjoy. Highly recommended.
