Well...as it turned out to be my only
book club read for 2012, my answer is Black Rain
by Masuji Ibuse (translated by John Bester). This selection was nothing that I would chosen for myself, incredibly heart breaking, but so worth the read
As I stated in my reveiw on GoodReads:
Although very sad, and at times difficult to read, Black Rain was also quite informative, and a testament to the human spirit.
