Mary Roberts Rinehart 
Amazing Interlude [PDF ebook] 

If duty called, would you leave the confines of your cushy life to dedicate yourself to the service of the greater good? That’s what Sara Lee, the altruistic heroine of Mary Roberts Rinehart’s The Amazing Interlude, decides to do amidst the terror and tumult of World War I. Based on the author’s own experiences as one of the first prominent female war correspondents, this novel provides a fascinating glimpse into the horror of war — and a heartening look at the miracle of human kindness and connection.
