I read this book last summer, a very interesting read.
I knew about the Russo-Turk-German-Brit angle of the story but war surprised to learn of the French involement in Lebanon and Syria.
As a side note I loaned it to my nephew who is SF. He brought it back from Afganistan with a AK round thru it, it was in his ruck. Bit of irony there was discussed over some Jamisons.
