African Pursuit is the final book of the Bonaventure trilogy. In this spine-tingling sequel to The Promised One and The Valley of the Ancients, an evil professor with an invisibility robe and his gang of villains clash once more with the intrepid family. This time their life-and-death struggle begins on the great plains of East Africa and ends in the dark heart of the tropical rain forests of the Congo. Like the two previous stories, this exciting adventure tale is packed with fascinating facts about geography and natural history.
