Odysseus is in Greenland, traveling with his parents. There, he will have the unique opportunity to see the beauty of nature in all its grandeur.

But why, just as a herd of reindeer is about to cross a frozen lake, does a loud croak sound? Why, even though they are in the middle of winter, are the ice sheets melting? What's happening?

A story that could be true, since Earth's temperature is rising, glaciers are melting, animals are in danger, and humans too... Could it be that the Earth has a fever after all?

The book includes informative material about climate change, activities, and a conclusion by Eleni Svoronu, head of environmental education at WWF Greece.
