Two sisters grow up on a farm. They are very close to each other, and share everything, all their thoughts, dreams and ideas. Until one of them gets roped in to spy for her country.
Now this is the part which gets confusing. Is she spying for the British government against the Nazis in WWII? Or in Spain? Ancient Rome? Pirates? The author has tried to depict this story as one that is old as time, and keeps repeating, cutting across nations and generations. But always of two sisters who grew up on farms and are very close.
Beyond a point, the back and forth gets hard to keep track of amidst the story, and I lost interest. I kept reading in the hope of some grand elucidation which ties it all together. But I was left wanting. The artwork and characterizations are outstanding. The story is unfortunately beyond my intellectual capacity.
