While we are frequently reminded that speculative realism doesn't, on some level, exist, it certainly hasn't stopped there being a out pouring of speculative realism books. And several of these look very exciting.
There is Tristan Garcia's recently translated and massive tome, Form and Object: A Treatise on Things.
Furthermore there are three books coming out very closely together, that all attempt to engage systematically with speculative realism, while also advancing their own argument.
Coming out in late July from Edinburgh University Press, there is Tom Sparrow's The End of Phenomenology: Metaphysics and the New Realism.
There is Peter Gratton's Speculative Realism: Problems and Prospects, due out in September from Bloomsbury Academic. You can read the actually pretty funny intro to his book here.
And lastly, but probably not least, there is Steven Shaviro's The Universe of Things: On Speculative Realism, which is due out in October from the University of Minnesota Press.
And the thing is, regardless on your position of speculative realism, all the books listed are probably going to be worth your time. None of the books, based on the bits and parts I have read or have talked about with the author, are some sort of fawning engagement with speculative realism. At the same time, all of them treat the this strand of thinking as serious, interesting, and, well, actually existing.
