The Forever Street — Frederic Morton

Berek, a young penniless Jew of eighteen is struggling to make a home of Turk Place, a desolate street that, in 1873 Vienna, was little more than a Gypsy encampment. But Berek believes fiercely in his own power to forge miracles. Taking the caretaker's daughter as his bride, Berek is confident he can thrive on faith. When a mysterious piece of stone comes into his possession, he and his wife believe their prayers have been answered; the stone may be a holy fragment of Jerusalem's Wailing Wall.
This relic, no larger than a brick, proves to transfigure the couple's lives. They make Turk Place their home and three generations of Turk Place residents share the legacy of the Brick. For six decades, the family perseveres in the face of tumultuous events -- World War I, the shattering of the Austro-Hungarian Empire, and the Great Depression. But Hitler's "final solution" forces them to make an impossible choice: flee the Nazis or remain and perish.
