Yes.
So basically the most of the book is partially about that the attack would start sometimes summer, not even in autumn. The Soviet military buildup culminated in the spring of '41, and the established two echelons, a bigger first one which main job was seizing/destroying the Romanian oil fields while simultaneously driving a punch into Germany, then the smaller second echelon could arrive and drive further to the west (with the start of the war mobilization would follow gaining millions of soldiers, and the new units would have been equipped by all those factories which were captured/destroyed by the war in our timeline by the Germans).
The concentration of the Second Strategic Echelon would have been completed on July 10. But the Soviet military theory ordains that the offense should start before the completion of this. And "Zhukov and Stalin liked to deliver their surprise strikes on Sunday mornings". The last Sunday before 10 July was on the 6th.
A certain General Ivanov said: "The German troops succeeded in forestalling us literally by two weeks".
