William Shakespeare 
Twelfth Night [PDF ebook] 
or, What You Will

In the kingdom of Illyria, a love triangle has everyone on edge. Orsino loves Olivia, a bereaved noblewoman who is in mourning for her dead brother. Olivia loves Cesario, who is actually a woman named Viola. Viola had dressed as a man in order to gain employment in Orsino’s household. Viola, of course, falls in love with Orsino, and he has no knowledge of the true identity of his "male" servant, Cesario. A romantic romp full of tricks, twists, and happy reunions, this unabridged version of William Shakespeare’s classic comedy was first published in England in 1623.
