This book was given to me by a friend at work, he put it in my pigeon hole with a note that read "I think this is extremely good - not a great work of literature but [a] very clever and gripping story". Just finished the book, he was right. Although the book was first published in the mid-1990's, I thought that the computer technology would have dated considerably, I was wrong. The computer at the core of the book was powerful and eerily onimpresent throughout the book. The book is written on a number of levels, it can be read as satire on the ugliness and megalomania of modern architecture. In its profile on Norman Foster, the Guardian noted "Philip Kerr adapted Foster as the thinly disguised lead character of his clever, high-tech thriller Gridiron. The character is a highly-driven, cold, utterly selfish monster who designs a building that thinks for itself...Foster was not amused" The Guardian 02/01/1999. It can also be read as a sci-fi novel as we are taking into purely scientific realms of how glass blocks out light at an atomic level to the principles of air-conditioning. The characters had a good substantial dimension to them. The humour crackled, arced and sparked throughout the book. The pace is gripping and unrelenting. A great well-written romp in a dystopic and dysfunctional building of the future - anyone who likes the work of Philip K Dick may well like this as well. Great entertainment throughout.
