sci-fi/fantasy/fabulist type stuff

I'm teaching a contemporary literature course next semester, and I've decided to make it a sci-fi/fantasy/fabulist type reading list, focusing of course on Asian American writers. I just ordered for the class Ruth Ozeki's All Over Creation, Larissa Lai's Salt Fish Girl, Karen Tei Yamashita's Through the Arc of the Rain Forest, Peter Bacho's Nelson's Run, and Greg Pak's Robot Stories (the screenplay). Do y'all know other stuff that would be good for a course on non-realist genres as social critique? I'm especially interested in stuff that engages with genetic engineering or other science and technology concerns. I'm also looking for shorter pieces to put in the course readings -- including essays, poetry, excerpts, etc. (I might include your piece on Karma of the New Mutants, slanderous, though it might be too deeply enmeshed in theoretical debates for first- and second-year college students.)
