I've recently come across two fun books by Margriet Ruurs.
My Librarian is a Camel: How Books are Brought to Children Around the World features the following Compassion countries: Thailand, Indonesia, Peru and Kenya.
My School in the Rain Forest: How Children Attend School Around the World features the following Compassion countries: Guatemala, Kenya and India.
If you sponsor children in these countries, you might want to check these books out.
