Another Jewish-person-in-the-Warsaw-Ghetto one for you, Franca, even tho' you've gone to bed.
this is a true story, which has more of its fair share of heartache but is also very uplifting. If it was a novel, you'd think 'Come off it, that could never happen.'- but it did and he lived to tell the tale.
It was out of print for years but now republished. Highly recommended.
