Having read and enthusiastically reviewed Bill Napier's The Lure, I promptly ordered all of his earlier books, of which the first to be published was Nemesis.
The setting is the near future, and the basic plot element a familiar one: a giant asteroid is believed to be on a collision course with Earth. There is a twist here, though - there is intelligence that its course is not accidental but has been modified by a resurgent and strongly nationalist Russian leadership to strike the continental USA, "accidentally" destroying the country without incurring the immediate response of a nuclear counter-strike. The problem is that no-one in the USA knows which asteroid has been selected, where it is, or when it might strike.
Oliver Webb, a British astronomer and astrophysicist, is one of a small international team assembled by the US government to work in secrecy to identify and locate the asteroid and devise a plan for diverting it from its course. The secrecy is necessary because of a fear that if the Russians found out that their plan had been discovered, they might launch a nuclear first strike for fear that the USA would do the same. Strong voices on the US side, alarmed by the possibility that the asteroid could arrive with little or no warning, are indeed urging a first strike by the USA while it is still possible.
Against this tense background, Webb and the rest of the team are in a race against time, which involves locating a rare and ancient book by an early Italian astronomer which is believed to hold information vital to identifying the asteroid. Scenes of their struggle against increasing odds are interwoven with those of political infighting in the US government and also with some from the past, in which the Italian astronomer faces trial for his heretical beliefs about the nature of the Solar System. As in The Lure, the arguments debated in these scenes are well thought through and convincing.
Arthur C. Clarke is quoted on the cover as having described Nemesis as "The most exciting book I have ever read". I wouldn't go quite that far, but it is certainly a page-turner and I can understand Clarke's enthusiasm since Napier, a professional astronomer, share's Clarke's interest in including a lot of accurate and realistic astronomical science. He also shares Clarke's rather weak development of his characters. The book is a very good read and while the writing has some rough edges, it is a remarkable achievement for a first novel. Not surprisingly, it is not quite as good as The Lure, mainly because the plot elements (not the asteroid but the human shenanigans) are rather more far-fetched, but it can still be confidently recommended to anyone who enjoys this kind of near-future science thriller.
I had heard good things about Nick Harkaway’s The Gone-Away World, published in 2009, so I bought a copy and settled down to enjoy the read. The story starts in a confusing future, when it is clear that something has gone drastically wrong with Earth; what is left of humanity survives in the Livable Zone. The first chapter concerns a team of people dealing with an unexpected emergency, but the reader is left dangling as to what this might be as the second chapter jumps back in time to the early childhood of two of the team members - the book's main protagonists - at a time when the world was much as it is now. Most of the rest of the book then works its way forwards to the events of the first chapter.
There’s some memorable writing but much of the book consists of digressive sub-plots rambling around all over the place. Some of them are amusing set-pieces but they turn the story into a patchwork quilt which only occasionally remembers that it's supposed to lead somewhere. I wanted to like this story and stuck with it for more than half the book, but finally admitted defeat and stopped reading when I realised that I was becoming more and more reluctant to pick it up and wasn't interested in discovering the ending.
I can see, in an objective sort of way, why the book attracted some enthusiastic reviews, but it simply failed to grip me. Which just demonstrates (if it needs demonstrating) that every book ever published has some readers who love it and some who don't.
