Read Rosemary's Baby for the next podcast episode. Honestly, if you've ever watched the (original) movie you almost don't need to read the book, its the most faithful adaptation I've ever seen. Almost word-for-word in a lot of places.
Having finished that, I'm now reading Lake of Darkness by Adam Roberts which, for those unfamiliar, is sci-fi with a speculative edge. I'm about 25% in and it has me hooked.
