The only girl in the world - Carol Drinkwater

The Only Girl in the World is a gripping romance set during the First
World War.
Dennis is an English soldier fighting in the trenches of the Western
Front. When he is on leave he meets H?l?ne, and it's love at
first sight. But the shadow of the trenches hangs over him. His leave
is over in a mere two weeks. When this battle is won; when this
war is over, he says he will come back for her. Dare H?l?ne fall
in love with this foreigner? Will she ever see him again? Will
he survive the trenches?
The world can be ending around you, but if you're in love nothing
else matters...
