Nada the Lily by H. Rider Haggard

Nada the Lily by H. Rider Haggard is a simple application for Windows 8. She is said to be robed in white, and to take the form of a young maiden, in fact an angel. She is said to appear to some chosen person, to whom she imparts some revelation; but, whatever that revelation may be, it is kept a profound secret from outsiders. I remember that, just before the Zulu war, Nomkubulwana appeared, revealing something or other which had a great effect throughout the land, and I know that the Zulus were quite impressed that some calamity was about to befall them.
