Polgara the Sorceress is not an entry point; it is a farewell letter. It assumes you already care about the world.
If you have read other Eddings books, you know their style. The dialogue often features "witty" banter that can sometimes feel circular. Characters tend to fall into archetypes (the drunk, the scold, the simple soldier). If the banter in the main series annoyed you, this book doubles down on it. polgara the sorceress pdf
