Another excellent book from Ian C.P. Irvine which really addressed a very scary subject that may ultimately raise its head in the future. Dealing with an advanced piece of artificial intelligence which had the ability to start a third world war and which would this time be a nuclear war. The artificial intelligence was known as Sebastian and it started with him carrying out a banking scam followed by two other scams of a worse nature. A lot of the book contained details of computer programs and related jargon which was somewhat difficult to understand but didn't detract too much from the story. The ending was classic Irvine which left the reader in somewhat of a void - Sebastian may have been still alive at the end as he put a telephone call into his creator! ( )
