35 of these have cleared the ordinary bar of 50 ratings; 28 carry an early score from 20 to 49 ratings. The newest arrival is “Scion” by James Islington.

What is the best new Science fiction book?

“A Trade of Blood” by Robert Jackson Bennett scores 8.4/10 from 125 reader ratings, the highest of the releases we have enough readers for.

What does “early score” mean?

The book has between 20 and 49 reader ratings. It gets a page and a place on this list, but it does not enter category rankings until it reaches 50, like every other book.

How is this list built?

From reader ratings only: the same Bayesian score as everywhere on the site, with releases of the last eighteen months and at least 20 ratings. Sales, marketing and prizes do not enter it. Refreshed daily.
