When Uno arrives in the forest on a beautiful day at the very beginning of spring, there are many magnificent and fascinating animals there to greet him... And one entirely unexceptional Snortlepig. Uno loves the forest so much, he decides to live there. But, in time, a little village grows up around Uno's house. Then a town, then a city... And before long, one by one, the animals begin to disappear.
Join Graeme Base in this beautifully illustrated, funny and moving story about environment, ecology, and human's ability to affect the world around them - for better and for worse - and learn basic maths concepts along the way, as Uno learns that it's all a question of balance.
