"Strong Motion" (1992) focuses mainly on a dysfunctional family, the Hollands, and uses seismic events on the American East Coast as a metaphor for the quakes that occur in family life (as Franzen put it, "I imagined static lives being disrupted from without—literally shaken. I imagined violent scenes that would strip away the veneer and get people shouting angry moral truths at each other."). A 'systems novel', the key 'systems' of "Strong Motion" according to Franzen are "... the systems of science and religion—two violently opposing systems of making sense in the world." The novel was not a financial success at the time of its publication. Franzen subsequently defended the novel in his 2010 Paris Review interview, remarking "I think they and readers may be overlooking "Strong Motion" a little bit."
