It’s April in Antarctica and, in places so remote that they can only be seen by satellites, lines of Emperor Penguins appear in search of the perfect ice for raising their chicks. A wise old Empress has returned to the ice at Halley Bay year after year; with the help of her mate, she works to protect her newly-laid egg against the bitter winter. But a changing climate is making the Antarctic Ocean warmer – winds are stronger and storms are fiercer... With luminous illustrations and an introduction by climate scientist Dr Phil Trathan, this is the true story of how the Emperor penguin colony at Halley Bay was disrupted after the sea ice collapsed, and how it’s necessary to protect the environment so that these extraordinary survivors will continue to be found in the Antarctic for generations to come.
