Reading Twitter this evening, I’ve become aware of an initiative called #AugustReviews, which encourages readers to go to Amazon and leave one review on one book that they’ve read. This post by Terry Tyler gives a comprehensive explanation of the why and wherefore (and this post by Rosie Amber gives a very thorough description of the how, and the how it doesn’t have to be as intimidating as one might think).
I’m ambivalent about Amazon myself. As a good trade unionist I try to avoid buying things on there (I live in Cambridge, not far from Heffers and a huge quantity of charity shops; I own a Kobo; generally this is fairly easy for me) but it’s an ill wind, etc, and Amazon has been very good for independent authors. Me included. And yes, we like reviews, and no, the book didn’t have to come from Amazon in the first place.
Mine is here (UK) and here (US) if you’re suddenly feeling the urge to leave a review of it. But I think I’d be behind this idea even if I didn’t have a horse in the race, and I’d encourage you to review any book you’ve enjoyed. At the very least it’ll cheer an author up.
