I feel as though, reading through all of the reviews of this novel, that I must not have read the same book as those who gave this book poor ratings. I believe it is honestly one of the best books I have ever read.
Yes, the characters are not normal--but they start off that way. It is the war that tears apart their family, turns them into killers, forces them to commit acts of depravity. Yes, Ross is a very complex character--but not to begin with. He begins as a simple, if not naive young adult in Canada and ends a mad, misunderstood soldier in Europe. Yes, Findley changes the narrative every 20 pages or so and yes, it can be confusing. But the book is about finding the humanity in the inhumanity of war by taking a look at a fictional but personal case. Findley's aim is not neatly tying up loose ends and making everything "fit" but unravelling tied ends and showing that nothing "fits."
If you enjoy happy endings that give easy answers and generic lessons, read another book. Findley's work is complicated, disturbing, and heavy and I for one enjoyed it. It's a book I still think about years after reading it and would recommend not "burning it to the ground" as some other critics have suggested, but leaving it until one is mature enough to comprehend its brevity.
