Follow the gold dust; there is a lot of it at stake. Key figures include fortune-seeker Walter Moody, who arrives in Hokitika and intrudes upon a meeting in a bar of 12 men furtively discussing a series of crimes. Anna, the whore with a dress of gold, has a backstory that will knock your socks off. The opium scenes are so convincing you wonder if Catton has had a puff. The dialogue is absolutely terrific.
And then there's the atmosphere. It's as if you, the reader, are with each character in turn in Hokitika, a dangerous place where everyone is an opportunist and everyone has secrets. You can smell the horses, the desperation, the rain. You feel damp. Catton plays with the signs of astrology and the occult. There is a seance. There are sly asides. Catton is playful and wilful, a fiendishly clever combination.
At time of writing, all stock had sold out but more copies (many more) are coming for the Christmas rush. You could call The Luminaries a "historical western thriller", but that's still not quite right. You'll have to read it and decide what it is for yourself. And it won the Man Booker ... Catton made us so proud.
