'Our discoveries have been great, but the risks and misfortunes many.'

John Franklin always wanted to be a sailor. As a volunteer in the Royal Navy at age fourteen, he found himself in the Battle of Copenhagan, but nothing could prepare him for the adventure of a lifetime, when he set off in 1801 with his cousin Matthew Flinders on HMS Investigator as it sought to chart the first circumnavigation of Australia.

Taking on responsibility for the chronometers, under the jealous eye of Flinders' younger brother, the young midshipman found all the action, adventure and excitement he'd hoped for in his new life at sea. It inspired him to become one of the great navigators and explorers of the 19th century.

However, he wasn't quite so prepared for the other challenges that life onboard had in store - the rivalries with fellow shipmates, the shortages of food, and the harsh realities of what they encountered in the colonies. Danger, disease and death seemed to follow in their wake, and even the Investigator was at serious risk of survival, and had to flee to Koepang in present-day Indonesia for repair.

The history books tell us that the first circumnavigation of Australia was completed on this voyage - but award-winning author Anthony Hill tells us how it was achieved. The Investigators is an unforgettable story of high adventure, exploration, shipwreck and survival as a young sailor comes of age.
