The Polgar books are good if you are looking for something to practice tactics puzzles with. The Seirawan books cover every aspect of the game and are verbose. Polgar is basically just chess diagrams like her pop's 5334 book but with a few words of explanation. You can get the Seirawan books cheap if you go for a used set as they must've printed a million of them over the past 15 to 20 years. I'd get the Seirawan books and definitely get either the Polgar or some other basic puzzle books to have something to practice from. The Polgar 5334 book is a great value but the problems get really hard once you get past the 300 mate-in-one's.
