Rift — Liza Cody

The lure of Africa's Rift Valley was irresistible to Fay. A journey across it offered the prospect of extraordinary beauty and adventure and the perfect chance to prove her independence.
The road from Nairobi to Addis Ababa is rough and rugged; the air oppressive and bug-infested. But it is the travelers Fay meets along the way that awaken her sense of danger. Caught in a web of death, chaos, and deceit, Fay begins to realize that there are some things you should never see - because once you see them, you cannot forget them.
