The book never quite lives up to it, though it's often witty and often cute. Holt, as is his wont, gets as much mileage as he can from the humor implicit in placing classical myths in a modern setting, though this is far from his only source of gags. Unfortunately, the three-hundred pages of gags don't seem to add up to one interesting story. Even compared to his other books, this one is somewhat tedious. If you haven't read Tom Holt's books before, this isn't the best place to start.
Nobody knows exactly why doctors say that.
If you are Osiris then you open up a retirement home for gods and godesses, and check yourself in. Holt starts off by doing the reverse and gives us supernatural beings who won't eat their rice puddings, and who fight over the correct reading of a map. This works well if you ignore the fact that all the Gods sound like they come from Oxford. The biggest problem for this book is that the gods have lost most of their powers but not all. Too often they can't wish the bad guys out existance because they aren't supposed to - its against the rules.
