"What is the book that changed your life? (not novels or religious texts)"
I think it's a wonderful way to connect in a less superficial way and learn a little more about each other. It's also a wonderful way to discover new books worth reading.

Most of the denizens of the Antarctic penguin coony sneer at Fred, the quiet but observant scout who detects worrying signs that their home, an iceberg, is melting. Fred must cleverly convince and enlist key players, such as Louis, the head penguin; Alice, the number two bird; the intractable NoNo the weather expert; and a passle of school-age penguins if he is to save the colony.
Their delightfully told journey illuminates in an unforgettable way how to manage the necessary change that surrounds us all. Simple explanatory material following the fable enhances the lasting value of these lessons.
