This is it. The review for the last book in the Great War trilogy, with said war coming to an end, both in Europe and North America. George Armstrong Custer plans to break the Confederate trench lines in Tenessee, massing hundreds of barrels to do so ( a move deemed illegal in U.S. doctrine ), culminating in the Barrel Roll Offensive, with Irwing Morrell at its helm. Canadian farmer Arthur McGregor becomes a figure of vengeance as he bombs anyone assosciated with his sons death. And, returning from the war torn battlefield along the Mason-Dixon line, a single soldier returns to his defeated country a changed man, vowing revenge on those perpetrated with his country's defeat and, most importantly, for all the wrongdoings against him.All I can say is, the book is an excellent conclusion to the series, successfully emulating the end of the Great War on North America, and making it plausible to all who reads it ( the series, I mean ). The next series of Timeline 191, American Empire, will have less violence, dealing more with the inter-war period, but that is for another day.I did not stating any of the book's flaws as I could not find any ( or I have simply forgotten them ). I also need not state the writing style of the book; you should be familiar with it ( if you read the previous books, that is ).
All in all, the Great War is an excellent series. The scenes, the implications, all are well described and imagined. I would highly recommend it. And, oh yeah. I will rate Breakthrough at 4 out of 5 ( not 5 out of 5, due to flaws (if I missed them)).
