The night ranger

Four friends, recent college graduates, travel to Kenya to work at a refugee camp for Somalis. Two men, two women, each with their own reasons for being there. But after twelve weeks, they're ready for a break and pile into a Land Cruiser for an adventure. Hijacked by bandits, they wake up in a hut, hooded, bound, no food or water. Hostages. As a personal favor John Wells is asked to find them, but he does so reluctantly. East Africa isn't his usual playing field.
