"Polgara the sorceress" is a book that can be liked by everybody that enjoys reading an engaging fantasy book, but will only be fully appreciated by those who have already read "The Belgariad", "The Malloreon" and "Belgarath the sorcerer" (yes, in that order).
The reason for that emphatic statement is simple: this book is the autobiography of Polgara, one of the main characters in those books. As such, "Polgara the sorceress" contains spoilers that could dim your enjoyment of the previously mentioned books. And believe me, "The Belgariad", "The Malloreon" and "Belgarath the sorcerer" are so wonderful that they fully deserve all the time that you need to read them first :)
"The Belgariad" and "The Malloreon" tell the story of a group of friends in a dangerous and magical quest, while "Belgarath the sorcerer" recounts the same story from the point of view of one of the main characters, who has the benefit of being almost immortal, thus having a thoroughly different perspective regarding the events that preceded that quest and everybody involved in it.
"Polgara the sorceress" is nothing less than a direct consequence of "Belgarath the sorcerer". Polgara is Belgarath's daughter, a sorceress and the guardian of the Rivan line. She didn't exactly agree with her father's version of what happened, and told her friends so. Despite that, Polgara wouldn't have gone so far as to write her own autobiography is Ce'Nedra (spurred by curiosity) hadn't plotted for her to do so.
Truth to be told, I specially enjoyed Polgara's take on what happened, and how she explained many things that Belgarath hadn't considered important. Also, I think that this book allows the readers to understand better Polgara's role in the preparation of the "Events", and how she became "Lady Polgara" and "Duchess of Erat".
In my opinion, this is a book that the fans of "The Belgariad" and "The Malloreon" will thoroughly enjoy. I always liked Polgara, and considered her to be a very likeable albeit perhaps overly mysterious character. I really enjoyed reading about her life, and I bet you will too. Recommended!
