both Steve Christenson's books are good reads, especially 'From the Congo Basin to the Highlands of Ethiopia' is a hell of a good read for those thinking a safari is just someone driving around pointing out which animals you should shoot...
'Buffalo, Elephant and Bongo' by Reinald von Meurers is a favorite...DIY hunts into the jungles of Cameroon, couple dozen trips....
anything by Tony Sanchez-Arino....he is a darn good writer....
