I'm still reading Polish Wiedzmin: Sezon Burz, the latest of the Witcher novels by Andrzej Sapkowski released fairly recently compared to the oldies. Loving it so far, definitely one of my favorite in the series.
Also picked up another Polish book from my grampa: Tropami Powstańczej Przesyłki, an autobiographical tale from one of the Warsaw Ghetto boy handling mail delivery. Crawling through ruined trenches, getting out of German capture, and watching death and destruction spreading around. Pretty chilling, if fascinating...
