Query: right or wrong, I don't know.

The book code lists this book, but the author listed does not match the author of the book before me. I bought the book for $110.00 from the law school book store, hoping to take it back Monday. I cannot tell, however, if the book on Amazon is the right book to purchase so I can return the one from the bookstore. I tried to get more information, but no other information was available, so I am left thinking I will be better off just keeping the book from the bookstore, even though it may be I could get a hardcover edition for less then one-half the cost. :(
