Only after thinking about this book for a day after I finished it do I think I finally begin to understand what the author was exploring. He was exploring the idea of history, who authorizes it, and how many versions of the "truth" go into a history. The main character, Tony, is looking back on his life (in the second half of the novel) and remembering things that he had suppressed or just tucked away from his youth. Many of these unearthed memories are fairly benign but what is disturbing is how he forgot them in the first place and how they colored and changed the history that he told about himself. The book also struggles with the idea of responsibility and who is assigned responsibility or blame in history--whether that is just or factual or simply a series of events that lead to each other. I wasn't sure I agreed with the book's conclusion, or what I think was the book's conclusion about this, but it certainly made me think.
