How do I do with HQL, many to many?

Question

Here is my database structure. Relation many to many. I want to make a selection of authors who have written the same book. With SQL, I did. How do I do with HQL?

   Query query = session.createSQLQuery("SELECT FirstName, LastName FROM authors, books, author_book as ab WHERE ab.authorID=authors.authorID AND ab.bookID = books.bookID AND ab.bookID = :id");
   query.setInteger("id", 1);
   List list = query.list();
   Iterator<Object[]> iter = list.iterator();
   while (iter.hasNext()) {
       Object[] obj = iter.next();
       System.out.println(obj[0] + " " + obj[1]);
    }
