Longitude does not seem to be a topic that would set the reader's interest and imagination racing, but Dava Sobel manages to make what is a seemingly boring topic into a tale that is gripping, exciting and educational.

She makes the era come alive and gives the reader a real understanding of those times. By so doing she provokes sympathy in the reader for the times and the immense achievements of the clockmaker Harrison whose life-long work was to change forever how we travel and trade.
