"Not in the same calibre as Ken Follet"
The Tuareg was an interesting source material. Especially in the light of the recent French intervention in Mali. However, it was not as sweeping an epic as the Sahara promised. I read it right after finishing Winter of the World by Ken Follet and I found myself continually measuring it up to it. I would have enjoyed it more if I had read them the other way round.
"A solid follow up to Fall of Giants"
I read it almost immediately after Fall of Giants. Maybe for that reason, the characters came alive and more vivid. I could get a better feel for the period and the circumstances surrounding some momentous events in WW2 than any history books.
