Black Locomotive

London is built from concrete, steel and the creative urge. Old technology gives way to the new. Progress is inevitable - but is it more fragile than its inhabitants realise? A strange anomaly is uncovered in the new top-secret Crossrail extension being built under Buckingham Palace. It is an archeological puzzle, one that may transform our understanding of history - and the origins of London itself. And if our modern world falls, we may have to turn to the technology of the past in order to save our future.

Ideal for readers interested in science fiction books.
