Critics and Bestseller are two ways to earn a place: a book's stronger one counts more. Buzz rewards recent bestseller weeks and prizes, so older books start at zero. The parts combine into the Must-Read Score, shown on a scale where the best book we found scores 99 and the last book to make the ranking scores 50.
