At first it took me a while to see the link between the different time strands; I blame the medium. Reading an ebook is different from reading the printed text. The link was rather obvious, the protagonist at different ages, different levels of experience and maturity.
One aspect that made Hamilton’s Fallen Dragon interesting was the political and economic system in place in this future vesion of our society. Not so different of what we have now, therefore the more credible. Nations states still exist, yet the decisions are made by and within the big companies, “public” services are provided rather by them, consumed by their employees and owners; participation in society and economic and social progress is via stakeholding in a company. Being an owner is having a voice, being able to progress through the ranks within the company, determining one’s own fate, being able to escape. There are, of course, prositive and negative sides to this way of organizing society. Hamilton very frankly spells them out, at least a few of them, without pushing the reader too strongly in a particular direction; embracing or condeming it. After all, freedom of choice and assuming responsibilty can arise from within this systen and from opposing it.
