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.

In this fictionalized story about a real humanitarian problem facing many countries in the developing world today, readers meet Mimi, an ordinary girl from an ordinary family in Africa. When her younger sister, Nakkissi, gets very sick after drinking unsterilized water from the stream, Mimi learns firsthand how quickly things can go terribly wrong. With no health care provider close by, her whole family must travel on foot to a nearby village to see the one nurse who can provide the medical care her sister desperately needs. Though Mimi is relieved when her sister recovers, she wishes they could get a health clinic in her own village. Several months later, it is Mimi herself who becomes the catalyst to make her wish come true. Author Katie Smith Milway, a former aid worker in Africa, has written the best kind of global education book for children, filled with information that engenders empathy and understanding. The picture-book format with captivating artwork by award-winning illustrator Eugenie Fernandes brings Mimi's story to life. Along with further information, a glossary and a map, an addendum includes suggestions for how young children can get involved, highlighting how inexpensive, easy-to-make improvements can transform people's lives. This terrific book would find many uses in elementary classrooms, including lessons on African culture, African family life and the basic health care needs of people everywhere. Most important, it offers opportunities for inspiring discussions about compassion, volunteerism and making a difference in one's own community and the larger world community.

Inspired by true events, One Hen tells the story of Kojo, a boy from Ghana who turns a small loan into a thriving farm and a livelihood for many. After his father died, Kojo had to quit school to help his mother collect firewood to sell at the market. When his mother receives a loan from some village families, she gives a little money to her son. With this tiny loan, Kojo buys a hen. A year later, Kojo has built up a flock of 25 hens. With his earnings Kojo is able to return to school. Soon Kojo's farm grows to become the largest in the region. Kojo's story is inspired by the life of Kwabena Darko, who as a boy started a tiny poultry farm just like Kojo's, which later grew to be the largest in Ghana, and one of the largest in west Africa. Kwabena also started a trust that gives out small loans to people who cannot get a loan from a bank. One Hen shows what happens when a little help makes a big difference. The final pages of One Hen explain the microloan system and include a list of relevant organizations for children to explore. One Hen is part of CitizenKid: A collection of books that inform children about the world and inspire them to be better global citizens.
