“When I first started following writers on social media, I imagined a deluge of profound quotes, writing tips and insights into the plight of wordsmiths. There was some of that. Mostly though, my timeline was taken up with their obsession with coffee: 'I want coffee/I'm having coffee/I've had coffee.' Then came photos of their favourite coffee mug/pot/shop/barista. So, if you've enjoyed a recently-published book, give credit to writers: the vampiric aficionados of the coffee cherry.”
