The Luck of the Weissensteiners
Christoph Fischer
Ashanti to Zulu: African Traditions - Margaret Musgrove, Leo Dillon, Diane Dillon

This book was probably the most interesting A to Z book I ever came across. Each letter stands for a different African tribe or subculture, and each brief entry covers something special about the tribe and its culture. This is done only in a single paragraph, so don't expect any great depth, but each entry is also accompanied by a colorful illustration depicting the tribal traditions.
Very enjoyable book to read to the young readers.
