Baroness Emmuska Orczy 
A Bride of the Plains [EPUB ebook] 

The story is set in Hungary and the scene is laid in a village close to the Maros.
On this particular fourteenth of September it is Andor’s turn to go unwillingly into the army for three years. On the eve preceding it, at the village merrymaking, as the whole population spends its last happy hours trying to forget the hideous events that will occur in the morning, he tokens himself to Elsa the village beauty.
When Andor returns from Bosnia, his village has changed, but so has he.
