I've enjoyed several of Paul McAuley's novels, and bought this book the instant I saw it. The back cover promised an exciting, intelligent story. After 70 pages I did something I rarely do--I put it back on the shelf. This book needed a strong editor.
If the following excerpt from page 68 excites you, or if you love Kim Stanley Robinson's novels, or if you have a lot of time and patience, you would probably like this novel.
"Soil was not a random mixture of inorganic, organic and living material; it was highly structured at every level, fractally so. Stratified and textured and dynamic, it supported a myriad complex chemical reactions that were still not completely understood, mediated by soil water and air moving through pore spaces that occupied up to fifty percent of soil by volume. Soil water also transported material through processes such as leaching, eluviation, illuviation and capillary action, and supported a rich and highly diverse biota--hundreds of varieties of soil bacteria of course, and cyanobacteria, microalgae, fungi, and protists, as well as nematodes and worms, and insects, and other small arthropods--that recycled macro- and micro-nutrients, decomposed organic material, and mixed and transported and aerated mineral and organic components. In natural conditions on Earth, it took about four hundred years to produce a centimetre of topsoil; a thousand years to produce enough to support agriculture...."
I see that there is a sequel to this novel. If passages like those above had been excised, and the exposition tightened up, perhaps the story could have been told in one better volume.
