Non-Spoiler Summary In A Nutshell:
“All You Zombies-“ follows the wild and convoluting exploits of a temporal agent sent to recruit a young man known as “The Unmarried Mother” – a writer for confession magazines. Posing as a bartender the agent coaxes the unsuspecting writer into revealing his own turbulent history. Being a little bit tipsy, The Unmarried Mother is tricked by the agent and taken into the past to set in motion a complicated and time-line-polluting series of events that eventually lead to his own birth. Wow! If it all sounds a little bit confusing that’s because it is! Nevertheless, this is one story that very clearly (and quite humorously) demonstrates why time travel will never be possible!
I was polishing a brandy snifter when the Unmarried Mother came in. I noted the time—10:17 P.M. zone five, or eastern time, November 7th, 1970. Temporal agents always notice time and date; we must.
The Unmarried Mother was a man twenty–five years old, no taller than I am, childish features and a touchy temper. I didn’t like his looks—I never had—but he was a lad I was here to recruit, he was my boy. I gave him my best barkeep’s smile.

Maybe I’m too critical. He wasn’t swish; his nickname came from what he always said when some nosy type asked him his line: “I’m an unmarried mother.” If he felt less than murderous he would add: “at four cents a word. I write confession stories.”
