Ferociously paced, Terminal Velocity delineates six wonderfully engaging characters: Artemis Foote, for whom being rich, talented, and beautiful is a kind of game; Jordan, a messianic fugitive who becomes Ellen's lover; Amethyst Woman, a Marxist/Leninist dentist; Ross, a red-diaper baby and now a columnist for Ramparts; and Pearl, an art history professor turned hippie.

At the center of this vortex is Ellen, prior to her transformation happily married and a rising young editor at a genteel publishing house in Boston. Together with these women, she is caught in the political and moral tailspin of the Sixties, living in a sexualized world-without-boundaries that leads them, eventually, to destruction, acceptance, and even redemption.
