Our Land of Palestine [EPUB ebook] 

It is the year 1915, and the British and Ottoman Empires clash in a deadly struggle in the Middle East.
Tasked with keeping the Ottomans out of Suez Canal, Major Andrew Selkirk discovers that his real assignment is to retrieve a Bengali spy working for those who vow to see British rule out of India.
After landing on the west coast of Palestine, Selkirk discovers the Ottomans have taken the spy captive. Even more troubling are the plans by Ottomans and Germans to draw Afghanistan and Persia into the war against Great Britain.
Fighting a personal feud with a vengeful German, Selkirk leads his men across strife-torn Palestine: a land that everybody claims as their own.
