I read 'Resistance' recently by Owen Sheers, about 340 pages so longer than you want but would appeal to women of a certain age I suspect:
1944. After the fall of Russia and the failed D-Day landings, a German counter-attack lands on British soil. Within a month, half of Britain is occupied.
Sarah Lewis, a 26-year-old farmer’s wife, wakes to find her husband Tom has disappeared. She is not alone, as all the women in the isolated Welsh border valley of Olchon wake to find their husbands gone. With this sudden and unexplained absence they regroup as an all-female community and wait, hoping for news.
I'd agree with previous posts re Somerset Maughan short stories, and matt Seaton's book is great.
Other stuff:
Catcher in the rye which is pretty short or In cold blood by Capote. I have been catching up on classic American literature of late and really enjoying it.
