Year's Best SF 14 by David G. Hartwell, Kathryn Cramer
This is lots of fun, and another reminder of how good short-form SF can be. I always look forward to this anthology coming out. Highlight for me here was the Cory Doctorow story, The Things That Make Me Weak, a great story that does much better (and with fewer trees felled) what I think Stephenson's brobdingnagian Anathem tried to do.
