Hank is a blue whale, and it's his birthday! But when his friend Jasper, a sperm whale, doesn't show up at the party, the other whales must find a way to rescue him before it's too late. Can they save him and the party?

In this book, children of different ages will learn the characteristics of whales and the environmental changes humans have caused in their world. It is also a story of teamwork and dedication to one's family and friends.

Testimonial from Brian Skerry, an internationally acclaimed maritime photographer and Emmy Award-winner for "Secrets of the Whales."

"The Big Birthday for Blue Whale is a wonderful journey into the lives of whales. A magical tale that draws you into the story from the very first page while weaving in real science and environmental threats to whales and the ocean. Brilliant storytelling that will leave you enchanted and informed."
