This is the third book in the five book Einarinn series. I have enjoyed this series from the beginning, and am greatly looking forward to the sequel. Juliet McKenna has a vivid imagination, and a knack for storytelling; each book in the series has been better than its predecessor as she has developed as a writer. Gambler's Fortune has some subtleties to the plot which are best appreciated by first reading Thief's Gamble and Swordsmans Oath. The underlying themes of the series are that of cultural change and also of conflict between cultures, and these appear in many ways. There are changes in agriculture displacing peasants who move on or become highway robbers. There are 'settlers' moving in to the mountains where hunting and trapping are the traditional way of life, and the supposedly 'unowned' land is no such thing. Above all there are the Ice Islanders who have very poor land, historic grudges and are busily, but quietly, moving in on the varied nations of the mainland. Gambler's Fortune follows Livak, who is trying to discover more about aetheric magic, which is used by the Ice Islanders. It is known that it once was the main form of magic, and Livak is hoping that by visiting two of the least 'modern' nations she can find old songs which hold useful spells. Juliet McKenna has created a real and fascinating world in which people are busily getting on with their lives, rather than stopping in awe because a quest is passing through. The main characters are all very human people and are not the porcelain Princesses of high fantasy, but instead are travelling thieves, swordsmen, gamblers, singers and one Mage who is a bit startled by the realities of life outside his ivory tower. Great fun, highly recommended.
