  • Buzz0 out of 100 · counts 10%

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.

On our reserve shelf: it's well reviewed, but isn't currently a prize winner, a lifetime bestseller or a book everyone's talking about, so we don't rank it. We check again every month, and it can still turn up in your 50 once you've read most of our ranked books.
