We'll I'm always reading many books at the same time but the latest one I purchased is Count Zero by William Gibson. The 2nd in the Sprawl Trilogy (Neuromancer, Count Zero, Mona Lisa Overdrive). I highly recommend his books especially the trilogy. I thoroughly enjoyed the first one Neuromancer and so far enjoying Count Zero.
The other fiction book I'm still reading is The Face by Dean Koontz. He's a weird author and it's a weird story. A little too long imo but I'm starting to get into it.
