The Guns of August - Barbara W. Tuchman, Robert K. Massie The Minor Adjustment Beauty Salon (No. 1 Ladies' Detective Agency) - Alexander McCall Smith

Audible is currently running 2 books for one credit sale on certain titles and I was able to find two titles that I wanted.

 

I chose Guns of August for my history challenge and The Minor Adjustment Beauty Salon because it is already on my wish list. If you have found to the No1. Ladies Detective Agency series hard to get into, try the audio version.
