"Logan's Run" (1976) explores a society where everyone dies aged 30. In the most campy, over-the-top 70s scifi romp imaginable, it explores fear of ageing, fear of death, fear of infantalization... and fear of Baby Boomers.

M. R. Carey is the author of "The Girl with All the Gifts" (previously discussed on this program) as well as the Koli Trilogy. He joins the show, along with Ashland Viscosi, to talk about his approach to science fiction.
