How does the author address the theme of historical connectedness in the novel, Moon Tiger?

One of the most-repeated thematic elements of the novel is the idea that one is bound to all others in such a way individual history and collective history cannot be told independently. This is, in fact, the central conceit of the novel. The book opens with Claudia’s reflections on the seemingly egotistical of combining biography with world history and ends with her assimilation into collective history through death.
