Fortunately, I had the second volume of the three-part already at home. Wool or in German Silo left behind huge plot holes and unanswered questions. Bought If I did not have the second volume already at home I would not have him. Shift takes the reader back in time. Mr. Howey actually manages to cram most of the plot holes. The big picture now gets sense that you missed so painfully in the first volume. Most questions are answered, but so completely 100% does not lock the story, because the logic or the motives of the protagonists, who lifted the world out of joint, are not transparent. There remains the question of why and that's unsatisfactory. Still, I am curious how Mr. Howey will bring the story to an end in Dust.
