OK book. Funny in places. Basic gist is that the Gods of Mount Olympus live in a filthy, rundown flat in London. They hire a mortal cleaner and then she gets killed by Zeus. Her kind of boyfriend has to go on a hero quest to the Underworld. Hilarity ensues.
I think you'd like this more if you had a strong background in Roman mythology, which I did once upon a time but have since lost - it was in 8th grade Latin, after all.
Overall a C.
