I'm currently on The Second Angel by Phillip Kerr.
It's an interesting read,but if you're not big on science,dystopia and futuristic settings,I think you'd better give this book a miss.
It quotes many medical references and other books and some Bible thingys,which can be annoying at times because you have to refer to the footnotes to understand that particular word(??) and its derivatives,but it is a highly interesting read.
