Artscroll: Budapest '44 by Moshe Holczer

The young Slovakian businessman planned to join his wife in London, but the Nazis marched into Austria and life would never be the same. Mandated by his illustrious father to remain in Europe to help his people, R' Shmuel Binyomin (Wolf) Frey embarked on a saga of rescue and relief that had reverberations beyond his wildest dreams.

Who was the mysterious Raoul Wallenberg, and how did R' Wolf come to work with him? Why did the Hungarian Minister of Defense have such a startling change of heart? Did the gypsies have any redeemable qualities? Would his fellow Jews really turn him over to the Germans? Where was the safest place for a street child to be at night? What were those Nazis doing in that building across the street? A house made entirely of glass? How long could they fool the communists? Were those nuns to be trusted...?

Let us follow R' Wolf to Hungary, and marvel at the incredible hashgachah pratis, the Divine providence, that followed him through one menacing situation after another. With unshakeable faith, with remarkable foresight and bravery, against impossible odds, he resisted Evil incarnate. He never thought of himself as a hero, but his courage and ingenuity will remain with you forever.

Budapest '44, his story, is an unforgettable tribute to the human spirit.
