The book tells a story of two marine biologists who spend their professional lives doing whales research. Readers are introduced to humpback whales, minke whales, blue whales, sperm whales, killer whales, dolphins, ect. Not only is the secret life of the sea giants brought to light, but also message to protect their habitats is sent out too.
Readers would be amazed at the expeditions that the Jenner family have made to learn more about the whales and to protect them. The book could have been better if it had been organised chronologically. I often got confused as to how the book was organised in terms of time. Having said that, the book was enjoyable to read.
