Also in honor of WWI veterans, here are a few books that take place around WWI.

Her investigations take her back to her past as a nurse during the war as she uncovers intrigue at the cooperative farm called the "Retreat." Find it at your library.
Legends of the Fall, yes, was a movie, but first it was a novella by author Jim Harrison. Also set during WWI, it follows three Montana brothers who ride over to Canada to join the war effort, and the paths their lives take after the war has ended. Find it at your library.
