The Russian Origins of the First World War by Sean McMeekin (The Belknap Press of Harvard University Press 2011). A somewhat heavy handed effort principally dealing with policy matters with a decidely anti-Russian slant (Sazonov and Krivoshein portrayed as unprincipled bad guys who, because of the age old Russian desire to control the Dardenelles, precipitated the War by secretly mobilizing Russian troops early). However, there is an interesting discussion of the Russo-Turkish Front and the Russian efforts in North Persia, which is rarely discussed much less analysed. McMeekin has taught in a Turkish University and is sympathetic to the "Sick Man of Europe". An interesting and different take on the accepted wisdom of the origins of WWI with some relevance to modern times given the results of the Sykes-Picot Agreement partitioning the Ottoman Empire.
