1 and 2 are fine, with only one book being read in 1, and more than one book in 2.
3 is a wordy way to say 1: "a book" is all you need, not the word "one."
1. My brother is in the library, reading a book.
2. My brother is in the library, reading books.
3. My brother is in the library, reading one book.

What is the difference between #1 and #2? Does #1 mean #3? Or Is 'a book' in generic use in Sentence 1? In Sentence 3, 'books' is in generic use, isn't it?
