A bit dated review (from 2012) but I believe the more affordable paperback version of Watkin's book only came out last year, so it's really only been available for the casual reader for not too long.
John D. Caputo reviews Christopher Watkin's Difficult Atheism: Post-Theological Thinking in Alain Badiou, Jean-Luc Nancy, and Quentin Meillassoux HERE.
