In this the twenty-fourth edition of his celebrated annual Mammoth Book of Best New SF (its 28th as The Year's Best SF in the United States), award-winning editor Gardner Dozois presents 33 of 2010's most outstanding pieces of short science fiction, along with his typically informative notes on each author. Many are the work of award-winning writers, but there are also some surprising newcomers. The collection is prefaced, as ever, by Dozois's Summation of 2010 in SF, a review of the year's highlights in publishing and film -- including non-fiction, media and awards -- obituaries and an insightful look at emerging trends.
