I picked this book up on a whim because I liked the sound of the basic premise. Having now read it I know for sure that it's one of the most original ideas for a novel that I've come across in a long time, and neatly executed as well.
The classic Greek gods, Zeus, Apollo, Aphrodite, Eros, Artemis etc. are living in a rather dirty house in London, just about keeping up with their godly duties, though nobody believes in them anymore. A couple of mortals get mixed up in their petty bickering and things spiral from there. The way these classic gods and their legends are mixed in to modern day London is brilliantly entertaining, and the plot picks up speed and keeps it going. More than many books I've read recently I struggled to put it down.
It's not quite perfect - in some indefinable way it just seemed a little simplistic at times - but definitely comes highly recommended.
