Jacob's Hammer

This audiobook is narrated by a digital voice.

Gustav Loeb, a young Swiss technician, accepts what seems like a routine assignment: repair malfunctioning punch card machines at a German facility. But when he steps inside the gates of Dachau, he enters a world of unspeakable horror, a place where data fuels death, where women wear Stars of David as trophies, and where life is tallied and extinguished with mechanical precision.


Caught between ambition and conscience, Gustav faces an impossible choice.

Tasked with fixing the very systems that enable genocide, Gustav must navigate the brutal hierarchy of the Nazi camp, from psychotic guards to desperate prisoners. His presence stirs suspicions, and soon he becomes entangled in a web of violence, secrets, and a haunting rumor, a mysterious boy said to have burned down a guard tower and killed a Kapo. Whether the boy is myth or martyr, Gustav knows one thing: his time is running out.


In Jacob’s Hammer, history’s darkest chapter is seen through the eyes of one reluctant witness.

Gripping and harrowing, this novel traces Gustav’s journey from neutrality to moral reckoning. In a place engineered to erase humanity, he must find a way out of the maze of inhumanity.
