Who Goes Here? was republished in 1988 with a short story The Giaconda Caper.
In the 24th century, men join the Space Legion to forget. A memory-erasing machine makes sure they do just that.
The machine purges the memory of all traces of guilt, but for Legion recruit Warren Peace it has wiped out everything. He must have had a very nasty past indeed – if only he could recall it.
Into battle with the Legion, Warren faces vicious predators in fearsome conflict without the slightest idea why he's been stupid enough to sign on in the first place!
