Rescued from the Reich

Came across a copy of Rescued from the Reich: How One of Hitler's Soldiers Saved the Lubavitcher Rebbe, which was published a couple of months ago by Yale University Press. The blurb says:

The escape of Rebbe Schneersohn [the 6th Rebbe -- MS] from Warsaw has been the subject of speculation for decades. Historian Bryan Mark Rigg has now uncovered the true story of the rescue, which was propelled by a secret collaboration between American officials and leaders of German military intelligence. Amid the fog of war, a small group of dedicated German soldiers located the Rebbe and protected him from suspicious Nazis as they fled the city together. During the course of the mission, the Rebbe learned the shocking truth about the leader of the rescue operation, the decorated Wehrmacht soldier Ernst Bloch: he was himself half-Jewish, and a victim of the rising tide of German antisemitism.

I took it home. Anyone read it?
