 FROM  books,book_category,book_click  WHERE  enable=1 AND category_id=7
AND books.book_id=book_category.book_id
ORDER BY  strong texttotal_views DESC

Answer 1

Checkout the mysql WITH ROLLUP

UPDATE

After reading your quesion again it might be as simple as adding GROUP BY books.book_id

SELECT  books.book_id, url, title, short_desc, img, featured, SUM(views) as total_views
 FROM  books,book_category,book_click  WHERE  enable=1 AND category_id=7
AND books.book_id=book_category.book_id
ORDER BY  strong texttotal_views DESC GROUP BY books.book_id

SELECT  books.book_id, url, title, short_desc, img, featured, SUM(views) as total_views
 FROM  books,book_category,book_click  WHERE  enable=1 AND category_id=7
AND books.book_id=book_category.book_id
ORDER BY  strong texttotal_views DESC GROUP BY your_grouping WITH ROLLUP;
