Waiting for the Rain — Sheila Gordon

Tengo and Frikkie are childhood friends -- one is black, one is white. Tengo, a "boy" on Oom Koos's farm on the South African veld, and Frikkie, the farmer's nephew, who one day will inherit the family's land. Though they live in different and conflicting worlds, their friendship is forged when they are too young to know that there are lines that must not be crossed.
