Finn and his younger brothers, Leo and Ooley, love reading stories about animals living in forests, on mountains or in the arctic.

"When I grow up," says Finn, "I want to be an explorer and travel around the world. I want to see wild animals and strange birds."

"Why wait?" asks Leo.

And so, the next morning, they wake up early and set out on a snowy expedition to search for wild animals. In their grandfather's time, the forest was full of animals -- but today the forest is quiet. Where have the animals gone?

This gentle adventure story about the effects of climate change ends on a hopeful note.
