While the war seemed rather static in the second book, major events fill Worldwar: Upsetting the Balance from the first scene. Turtledove still follows all of his major characters, depicting the war from many perspectives. But now the personal struggles are more often entwined with higher concerns, giving this volume more depth as well as more suspense. Turtledove also returns to some humorous social commentary, something prevalent in the first book but strangely absent from the second. One sequence details the horrors experienced by one of the Race's psychologists who, as an experiment, is trying to raise a human baby. At another point, the Race's reaction to the concept of science fiction concisely illustrates the Race's views regarding the human ability to innovate.
