...because I’ve just finished Philip K Dick’s The Three Stigmata of Palmer Eldritch and the vicious little things sound like they might be useful to have around at home, to turn loose on visiting relatives (Pomeranians have bark but no bite). I also wouldn’t mind the predatory but forlorn Martian jackal-creature that asks its victims telepathically, "May I eat you?"
Apart from introducing us to these strange beasts, P.K.D. discusses how to attain God-ness in this fabulous book, which got a little too abstruse for me near the end but which is still topline science fiction. If you want to Dick-delve, this is a good starting point.
