Query: Real Life "Adventure"

Not an adventure when compared to fictional safari tales in which the intrepid travellers fight off fierce lions and savage "natives" in every chapter. Instead, an enjoyable and realistic account of Greene's arduous and near-disasterous trek through Liberia. Greene travelled with his cousin, Barbara Greene, who also wrote an account of their journey--Too Late to Turn Back. Interesting contrasts between the two books if you can find copies of both. I had to order a copy of Barbara's book from a used book store in England.
