this is the last book in Moon's "deed of paksenarrion" trilogy, so my first advice would be to read the other 2 books before picking this one up. the book *does not* stand alone, and has frequent refrences to people and events in the preceeding books. there is an edition out there that contains all three novels, and i'd definately reccomend picking that up, as these aren't really seperate books, just a continuation of one long story.
all that being said, i highly reccomend this trilogy. Moon has written a strong, convincing heroine that rides to her own rescue. the story of the sheepfarmer's daughter that leaves her small-town life to train to be a warrior and ends up being one of the greatest knights in history is a fun, engaging read. if you come to this third book having read the first two, you know that you will be unable to put it down any time soon (the cliffhanger ending of the second book is really frustrating if this one isn't in hand). 'oath of gold' doesn't dissapoint: it's a solid conclusion to paksennarion's big tale.
