In the first two books of the TimeWorm trilogy, an accident with a time machine of the mid-twenty-first century causes Theo and his robotic dog, Murphy, to time jump into the dangers of Nazi Germany. Theo meets a German teen named Gracie, who is also running from Hitler's Third Reich. The trio escape to America on the Hindenburg.

This final book of the trilogy has Theo, Gracie, and Murphy back on American soil. The teens plan to return to Theo's future world after he is a spy in a summer camp while Gracie visits a boarding school. Reunited, the teens find shelter and hope in an abandoned shack until Murphy and Theo pick up a scent of the horror of Germany they believe they have left behind.
