It’s been awhile since I have been able to recommend new WWII fiction, but I just finished and enjoyed this new book by Kristin Harmel: The Room on Rue Amélie.
I have read A LOT of WWII historical fiction and keep a running list of the books in that genre that I recommend.
For better or worse depending on what type of books you prefer, Harmel’s new book is lighter reading than many of those in my list referenced above; it reads more like a romance, but its plot and themes are deeper being set in a turbulent and horrific time.
