Book 1 of 4 in the Invincible Abdullah series. When Abdullah travels from England to visit his cousin Hasan in Pakistan during summer break, there is more than just a friendly family visit in store. A luggage switch at the airport, a half million dollars in smuggled cash and an unexpected fight in the bazaar lead the boys into some of the wildest territory in the highest mountains in the world. Armed tribal conflict is the result. Abdullah's knowledge of karate and Hasan's quick wits as well as the strength and courage of their companions, Gul Muhammad and Abd al-Haqq are sorely tested. That test becomes a life and death struggle against the elements and the evil of men.
