Although Jackaroo is set in an imaginary feudal kingdom, Gwyn, the Innkeeper's daughter, is very much a modern heroine with an independent attitude and adventurous spirit. She lives in a world of rigid social classes where the people have no choice but to obey the rulers. But Gwyn has a compassionate nature that demands justice, and when she sees the suffering and inequity in her world, she sets out as a female Robin Hood to right these wrongs. As a result she must renounce her family, her home, and her inheritance, but she begins a new life in a new land with the man she loves.
