Query: Excellent intermediate text

Having used this book in a graduate algebra course, I feel that it is an excellent text for those who have already had a rigorous introductory exposure to modern algebra (say, via Dummit and Foote or Fraleigh). Grillet writes clearly and concisely and leaves several challenging (but doable) proofs to the reader. His wry sense of humor is also reflected in his writing.On some subjects, it is more of a survey of topics (such as category theory, universal algebras, exterior products), the point of which only becomes clear after one needs to use these tools in other areas.If you are new to the subject, however, the texts by Dummit and Foote or Fraleigh, e.g., are more appropriate.
