The Lieutenant by Kate Grenville

A shy, brilliant young lieutenant and amateur astronomer posted to an early British settlement in Australia forms an intense, language-based friendship with a local Indigenous woman; through learning her words and ways he gains a human, intimate perspective on a people the colony views as other. Torn between scientific curiosity, personal attachment and the demands of a brutal colonial administration, he faces moral choices that expose the costs of empire, the limits of communication, and the fragility of compassion in a hostile new world.
