I read Kabloona by Gontran de Poncins a couple decades ago and it's stuck with me ever since. I don't think I've ever seen it mentioned online before. It's high on my list of books that should be top-rated classics, but as far as I can tell it's basically unknown. If you've never heard of it, seek it out, it's fabulous!

Edit: Since alecst has obviously already read Kabloona, I might as well give a few more that are on that "list": Winter Wheat by Mildred Walker, Goatwalking by Jim Corbett, and Hyssop by Kevin McIlvoy. Maybe you'd like one of them too.
