In Fugitive Pieces, Athos (a geologist) takes him to Zakynthos in Greece, and after the war moves to Toronto.
Jakob Beer is a 7-year-old child of a Jewish family living in Poland. His house is stormed by Nazis; he escapes the fate of his parents and his sister, Bella, by hiding behind the wallpaper in a cabinet. He hides in the forest, burying himself up to the neck in the soil. After some time, he runs into an archaeologist, Athos Roussos, working on Biskupin. Athos secretly takes him to Zakynthos in Greece. After the war, Athos and Jakob move to Toronto, where after several years Jakob meets Alexandra in a music library. Athos is also a geologist, and is fascinated with ancient wood and stones.
