Ayisha and Ahmed know there is trouble. Something is not right with this American archaeologist and his wife. Supposedly tourists. Why are they so interested in the ancient manuscripts of Timbuktu? Could they really be plotting to steal one? Well, they are more than old manuscripts to Ayisha and Ahmed#x14;they are a rich part of their own heritage. No way are the two teens going to let this happen! They risk everything to stop them, embarking on a desperate quest that takes them across the desert, through a deadly heat, a sweeping sandstorm and fi nally to the port city of Korioume to confront and trap the wily thieves#x14;and save a treasure of Timbuktu.
