“A fascinating and well-written book about the universal journey of adolescence. It is full of insights about humans as well as many other animals. There is much that human teenagers can learn from the experiences of adolescent penguins and hyenas.”
Yuval Noah Harari, author of Sapiens and Homo Deus

“It blew my mind to discover that teenage animals and teenage humans are so similar. Both are naive risk takers. I loved this book!”
—Temple Grandin, author of Animals in Translation
