Book excerpt: Mack Flores, who now lives with his mom and siblings on the Roper ranch in Texas, wants to tell his friends and family back in Mexico about his new faith in Christ. Clarence Roper plans a trip with his son Phil and his nephews, Del and Doug, to take Mack back to his village so he can tell them about Jesus. But right from the start, there is trouble.
