Shiel's last book published during his lifetime. "A combination of social reform and scientific fantasy concerned with youth-medicine." The Young Men are Coming! (1937) deals partly with contemporary social upheaval participated in by an advanced multiple-sexed Alien from Jupiter, who takes the side of science against superstition. The sf element here is much more sophisticated and imaginative than contemporary Genre SF, but is buried in a welter of eccentric social philosophy, and told in the decorated style of its author's youth.
