Produced in the '50's by the late sci-fic-sexology-comics impresario, this invasion spectacular is pugnaciously inventive but stiff as a buttonhook. The invaders, dimly seen as gentle insects, breed humans laboratory fashion, graft superior intelligence on the incubated zygotes, and deposit a mass of brilliant three-year-olds in Central Park. The tale holds in spite of Gernsbackese, and the lively enterprise of the author is celebrated in Sam Moskowitz' introduction.
