I haven't found much else out there on this topic: writing fiction about characters who don't share your subject position in terms of race/gender/sexual orientation/ability/age/etc. So I was glad to find this book and glad science fiction writers wrote it. It's got some writing exercises I can imagine using in a creative-writing class. There are people to whom I'd like to give a copy (anonymously). But I wish it was better than it was, more challenging, hadn't intentionally and for confusing reasons left out class...
