A good book should cause one to find a continuous string of further questions arising in the mind while and after reading it. A great one should cause the mind to positively fizz with them. And after only yet reading Elizabeth Marshall Thomas’ forward and Marcus Baynes-Rock’s introduction to his Among the Bone Eaters; Encounters with Hyenas in Harar, I have every reason to believe that my brain will be bubbling like a shaken soda bottle by the time my reading of the book is completed.
