So she began studying history.
"Writing was a whole new experience for an academic," she said.
"I hadn't written an essay for years. I was more used to producing a single page of bullet points; I think they gave me C for compassion."
She had found her true vocation, however, quickly learning the importance of not making people what they were not.
"When you are writing history you cannot bend the facts," she said.

Almost local
Mrs van der Laarse, a lifelong teacher mainly of intermediate-age children, took a very different path to becoming a published author (although she too had often wondered about her forebears, who were from Devon).
A Far North resident for "going on for 45 years," and therefore almost a local, she had taught at Kaeo, Kaitaia and Broadwood, and had been driven to put pen to paper by her concern at the dearth of reading material available for her students.
"So I decided to write for them," she said.
Trouble Patch, "pretty much set in Broadwood," with a cannabis plot playing a central role, was published in 2000, followed by Not Even, "a Taipa story," which made the Storylines Notable Book List, in 2002, and now Cuz, set in Fiordland, which went to reprint six months after its release.
She described Cuz as a tale of trust and survival, set in the wild and rugged Fiordland National Park, but it is no ordinary teen novel.
The story of two young people from very different worlds, it includes references to edible native plants, maps, and a glossary of its re reo Maori content.
Mrs van der Laarse's success is underpinned by the fact that teenagers readily identify with her characters, their credible rural settings, action and events.
She also obeys the first rule for authors, in that she writes about what she is familiar with (excepting the cultivation of cannabis). She and her husband Max, now living in retirement at Cable Bay, have shared a life-long passion for the outdoors, themes that are prevalent in all three novels.
