I really liked this book. Not only because I am from Edinburgh and so know many of the places described in the book, but also because it is a science fiction book on the scale of Greg Bear with a runaway plot much like Tom Clancy. The gradual disintegration of the Earth by the Moonseed makes a great plotline that Baxter follows through to the exciting finale. A great yarn. The sort of big book you take on holiday expecting to get halfway through in two weeks but then find yourself finished after two days of through the night reading. Few other books have done this for me - Clancy's Red Storm Rising and Sum of All Fears, Greg Bear's Eon, Asimov's Foundation series are among the few others. A word of warning though. Baxter doesn't seem to have a wholly consistent style across his books. I have just finished his novel Time and was frankly disappointed. He seemed to have a good idea that ran out of steam halfway through and resorted to hard sci-fi as a means to get through to the end with that one. But Moonseed is excellent and a thoroughly recommended read.
