To help his Holocaust-survivor grandfather, Menachem Kaiser battles to reclaim the family's apartment building in Sosnowiec, Poland. Discovering that his grandfather's cousin wrote a secret memoir while a slave laborer in a vast, secret Nazi tunnel complex, Kaiser meets a band of Silesian treasure seekers who revere the memoir as a guidebook to Nazi plunder. Telling an astonishing tale and introducing a host of memorable characters, Kaiser also considers such questions as: What does it mean to seize your own legacy? And can reclaimed property repair rifts among the living?

"Often hilarious, often poignant…. A light tone belies the book's seriousness of purpose: to tease out thorny issues of inheritance, reparations, and what it means to honor one's dead." —New Yorker
