This is the story of Jesse Martin who, at the age of 18, became the youngest person to sail solo and unassisted around the world. A young man who didn't know the meaning of impossible.

'Your courage and determination are an inspirational example for all young people to follow.' Bill Clinton, former president of the United States

'I was a member of a large community at the start who thought he was mad. I take my hat off to him.' David Adam, International Yachtsman

Jesse Martin was born for adventure. After learning to sail at fourteen, he travelled along Australia's tropical coast on a flimsy catamaran, and by sixteen he had kayaked through the remote islands of Papua New Guinea and crewed on a yacht sailing from Belize to Tahiti. But the biggest adventure of them all was yet to come.

Lionheart is Jesse's story. A story of courage, loneliness and danger, it is also an incredible, gripping, true-life adventure.
