Jo Walton takes a look at one of my favorite Samuel R. Delany books, Empire Star.
Addendum (from many dates): And there's more! Jo Walton on the need for more SRD. Jo Walton on SRD's Nova. A second piece by Walton on Nova. Walton on SRD's Babel 17. Walton on the SRD book everybody loves...or hates. Walton on a key SRD anthology. Walton on Stars in My Pocket Like Grains of Sand. Walton on SRD's autobiography (a book I highly recommend). Additional associational writings. Delany's latest. Sean Grattan on Trouble on Triton. Delany (and others) in The Paris Review.
