I went onto Amazon's French site to source a link for the DVD of Bertrand Tavernier's brilliant police thriller L.627 for inclusion in a forthcoming post, and here's one of the books that came up amongst the site's featured home-page recommendations.
No, it wasn't a recommendation based on my past purchases. I wasn't even logged in. And yes, it's a product that does exactly what it says on the tin... of the author we read, "En tant qu'actrice, Coralie Trinh Thi a tourné une soixantaine de films pornographiques, ainsi que longs et courts métrages."
So she probably knows what she's talking about. My French isn't so great these days but I imagine that her writing has something in common with that of Ernest Hemingway. Given that Hemingway never wore underpants and preferred to stand while typing.
The first sight of that Stephen Cartwright-style artwork made me think I was looking at The Usborne Book of Sodomy.There's a whole series of them, but I'm afraid you're going to have to explore it on your own.
