Secular Charlotte Mason

These two novels are written by Karen Bass, an author and librarian in Alberta.  I know Karen, and she's a lovely person and an amazing author--and I've watched her document her rigorous research process in an online community we both frequent.  Check them out if you have teens and need some updated reading material for the WWII studies:

Summer of Fire

Run Like Jager

Karen knows her market (Young Adult) very well, so these might be appropriate for younger readers, but I would definitely recommend prereading them before handing them over to a younger child.
