If you haven't read The Oracle, read it first because the complexity and brilliance of The Archon can only be fully appreciated if you understand this is a dramatisation of the tension between religious belief and unbelief. Fisher has imagined a Graeco-Egyptian world in which the god, or Archon, is regularly incarnated, and served by nine masked priestesses who interpret his will. Underneath their masks, the priestesses seethe with personal and political ambition, and few believe in the god anyway. Yet he exists, and it's only through him that rain can be brought to a dry land.
In the first novel, the Archon died, and his replacement - a mad little boy, Alexos - had to be found and brought back to thwart to potting of General Argelin and his lover, the priestess Hermia who is the god's Speaker. Mirany, the lowest priestess, doesn't believe in the god either but is made to and with the help of a drunken poet Oblek, a corrupted scribe, Seth, and a criminal lord known only as Jackal, brought him back.
All should therefore be well, but it isn't. The General is still plotting, and in the second novel, Hermia is poisoning anyone who gets in her way, and the land is still parched despite brief rainfall. Long ago, the Archon offended the Rain Goddess, and now Alexos is determined to make his peace with her by finding three lost stars. He leaves Mirany behind in a city under seige, and journeys with Oblek, Seth and Jackal across a desert haunted by strange beasts and powerful dreams. Corruption, betrayal and evil stalk them, and the boy-god's powers may not be sufficient to protect anyone - least of all himself.
The plot has a long fuse, and it's not until page 50 that it really gets going, but the tension and beauty of Fisher's writing is what makes it really remarkable. She conjures up both her desert world and the possibility of the supernatural with such conviction, you can almost taste the dust. A more complex series than The Snow Walker's Son, it's also about the loneliness of power and the need for friendship. She's one of those rare fantasy writers who can really write (she's also a good poet). Not all her novels are equally good, but this series is.
