Harrison's latest book, Hold the Line, is set during the contentious Springbok Tour of 1981. This year marks 40 years since the tour.
Despite growing public protest, the Government and the Rugby Union were adamant the tour would proceed.
The result was a well-supported protest movement pitched against a nation of die-hard rugby supporters.
Hold the Line details the polarisation in New Zealand 40 years ago.
Although the novel is fiction, the story is real to Harrison. After all, both she and her brother Laurie Harrison were part of the anti-tour protests.
“I was a protestor in 1981 and I was amazed at the passionate debate and the war-like atmosphere that descended on our normally sleepy country,” Harrison told NZ Booklovers.
“So many relationships were put to the test. It was a time full of drama and change with the potential for rich characters.”
Harrison says the talk at Muirs Bookshop will detail the tour's events and the research that went into writing the book, from the anti-tour protest movement to movements of the riot squads and the historical tragedies such as the Sharpeville massacre and the murder of South African activist Steve Biko.
Stop by Muirs Bookshop this Saturday at 3pm to listen and speak with the two authors.
