The title is a little deceptive. It is meant more literally than I would have expected. The story has to do with Britain's attempt to find an accurate way to measure longitude and so limit the number of lost and wrecked ships. Some people believed that the key would be in more accurate time keeping-including John Harrison, a rural self-taught carpenter with a passion for clockmaking. His concept was different than others in that he believed it was important to construct a timepiece that would not be affected by conditions at sea-especially weather and the rolling motion of the ships. He was successful and spent much of his life perfecting what are now called chronometers, but he ran into a snag with the contest which started his inventing.

Besides the most interesting story, Kevin Hawkes's illustrations are very well done. Most of them are impressionistic and capture the mood of the story. The cover, title page, and end pages are more detailed, and beautiful. Others are also arresting. All have certain highlighted details, some with a point to be made and some showing humor.
