I'm bit late to this one - Marusek first came to my notice in a short story anthology with an inventive and thoughtful story. It piqued my interest, so here I am!
Counting Heads, Marusek's debut novel, is a fantastic read. In some ways it's straightforward enough, if follows the fortunes of one man and his family through several decades (though, to be clear, it leaps - overall there is a broad sweep, but it's handled in a couple of denser "chunks.") Where it sets itself apart is how seriously David Marusek takes the job of writing SF. Not to say that the novel is po-faced, or anything like that. He's a good writer, there's a decent level of wit in this.
Instead, what I mean is that it's a proper, serious SF novel. It never shies away from the fact that it's SF; it has a lot of ideas in it and I'd guess that Marusek has read a lot of SF himself. He marries these sfnal themes with an excellent human drama, the characterisation in this is almost uniformly excellent. This can often, I think, be a weakness for a lot of ideas driven SF writers - that is to say that they are often not so good at producing characters who are anything other than mouthpieces for themselves.
The opening of the novel sees a famous artist, Samson Harker meet a woman on her way to great power. By the time that the novel starts, humanity has practical immortality. They can both look forward to a long, long life. This, naturally, means that what we would consider normal is discarded. It's unlikely that immortals would wish to spend the rest of their lives together, on a crowded planet producing children would have to be strictly regulated, so when they find themselves in position to produce offspring, it's not quite in the way that we'd consider normal. However, this would seem to imply - in some ways - almost utopian. Things aren't (of course!) quite so simple. It's set against the background of a terrorist attack which has led to intense paranoia about nano-weapons - which imposes surveillance on the population and leads to Sam Harker's downfall. He is "seared" a process which amongst other things separates him from his peers. He is now incapable of receiving the treatments he requires to stay young. So when the book moves into it's second and third parts, he is an old man.
Incidentally, the book does handle the "show, don't tell" thing quite well. It's clear that there has been some kind of attack in the past which has led, in part, to the kind of society that we see now, but this is only ever explained as well as it needs to be. Also, the society in which the book takes part is clearly complex, but even beyond this, it's obvious that the whole world is complex. There are hints that the future that we see here isn't *quite* so evenly distributed through the world as one would hope.
The "searing" (and there are quite a lot of new terms in the book, though some are obvious and made more so by context, "aff, "homcom" and so on) was part of an attack on the growing power of Eleanor Starke (Samson's wife). As the novel moves on, this is more pronounced. A crash leaves her and her daughter dead and severely disabled (only her head survives intact!) and the plot of the novel centres around a group of characters involved in its retrieval. If I were to criticise, I'd say that the ending does go a bit crash-bang-wallop, but it was fun getting there.
The confidence of Marusek is demonstrated, I think, in that there are many ideas that people would use to create a whole novel on their own (nano-tech, colony ships, AI). He instead chooses to focus on the human aspect of this (and that's including the integration of sentient machines, clones and immortality). Although the next book, (
Mind Over Ship) is a sequel, so he may look at some of these in greater detail.
So; a recommended debut! Enjoy!
