In 2016, Petina Gappah reached a deal with her UK publisher Faber & Faber to make her books, the story collection Rotten Row and the novel The Book of Memory, available in Zimbabwe—in Harare, Bulawayo, Gweru, Masvingo, Mutare, and Victoria Falls—at half the typical price. It was an extension of artistic responsibility and commitment, not to mention financial risk, that was cited in Brittle Paper‘s naming of her as the African Literary Person of the Year 2016. Gappah herself thought of it as an experiment that might hopefully become the springboard for a sustainable book distribution model.

This ethical investment may be why, this year, Gappah is calling out a Harare-based bookshop, Innov8, for overpricing her new novel Out of Darkness, Shining Light. She made a post on Twitter asking readers to not buy the novel at Innov8’s $50 price and to wait for a $20 arrangement with her UK publisher once the book is out there in February.

“I take great exception to this pricing because my books are not subject to the 40% book tax that I have been fighting against,” she wrote. “They are covered by Zim’s EU tariff, so there is no duty to pay. There is no justification for selling it in Zim at almost 3 times the normal price.”
