O. Henry 
Gift of the Magi [PDF ebook] 

The Gift of the Magi is a treasured short story written by O. Henry. A young and very much in love couple can barely afford their one-room apartment, let alone the extra expense of getting Christmas presents for one another. But each is determined to show their love for the other in this traditional time of giving; each sells a thing they hold most dear in order to afford a present, with poignant and touching results that capture their love for one another.
