goofy suggestion. those are both either grad or senior undergrad books depending on where you are. much better suggestion is

A Book of Abstract Algebra by Pinter (really gentle)

or

A First Course in Abstract Algebra by Fraleigh

I used on in high school and the other my second year of undergrad. They have lots of material but they also have good exercises and explanations.

Herstein was my undergrad book back in the early 90's. I remember really liking it. It's been a very long time, but my recollection was that the groups to rings progression felt a lot more natural to me than the rings to groups progression of some of the other books at the time.
