A review by josephfinn
The 1989 Annual World's Best SF by Frederik Pohl, Ian Watson, Brenda W. Clough, George Alec Effinger, Steven Gould, David Brin, Arthur W. Saha, Jack L. Chalker, Isaac Asimov, Tanith Lee, Donald A. Wollheim, Geoffrey A. Landis, Kristine Kathryn Rusch, John Shirley
3.0
Not a great anthology, but the storiy "Ripples on the Dirac Sea" is a brilliantly sad tale of time travel gone wrong.
