Query: Great Text for an Undergraduate

This was the book that really introduced me to how much fun mathematics could be. The main text covers all of the standard topics in a very clear manner, but the overwhelming strength of this text is the large number of excellent exercises, which range in difficulty from easy to graduate level. Most are labeled as to difficultly, which is unusual, but nice.I cannot emphasize this enough: to get the most of this text you should do as many exercises as possible of a difficulty level that challenges you. If you do, you'll have a solid foundation of abstract algebra that will be more than sufficient if you choose to pursue graduate studies in math (or another field) later.
