Vanessa Croft was born in Australia to expat parents, and was raised in Nigeria and Papua New Guinea.
That time in Africa helped flavour her novel Where in All the World, which follows a young colonial New Zealand woman who makes a poor match in marriage to a flagrant British explorer.
Although fiction, the heroine's experience's are similar to that of a real New Zealand woman, Gertrude Edith Grogan, who lived in Kenya after her marriage to Ewart Grogan - a British colonel who traversed Africa on foot.
She talks about the themes of gender, betrayal and exploration - and the unexpected way she came to know Gertrude's story.
