One Hen is the latest title from the creators of If The World Were a Village, Tree of Life and One Well.

It is the perfect way to introduce children to the concept and importance of sustainable development.

One Hen tells the story of Kojo, a young Ghanaian boy who uses a micro loan to buy a chicken, so he can sell the eggs to make money.

Through hard work, Kojo soon earns enough to go back to school.

He grows up to own his own farm, employing many people in his village, and contributing to Ghana's development.

The story illustrates how a small loan can have a huge impact on many people's lives if used in the right way.

Striking artwork and 'House that Jack Built'-style captions lead the reader through Kojo's progress.

At the end of the book, the story of the real-life Kojo is told.
