Twinning, cross-dressing, a love triangle and mistaken identity drive the action of William Shakespeare's ever-popular comedy Twelfth Night. In Illyria, Duke Orsino pines for love of Countess Olivia, who in turn mourns for her dead brother. When shipwrecked Viola arrives on the scene, believing her twin brother Sebastian to be drowned, she falls in love with Orsino, but disguises herself as a boy in order to be Orsino's page. Viola/Cesario becomes the object of Oliva's love while serving as a go-between; to make matters even more confusing, Sebastian and Antonio arrive in Illyria, where an old enmity persists between the former and Orsino. Olivia marries Sebastian, thinking he is Cesario. Meanwhile, the roistering nobles and servants at court fall into their own romantic confusions. All ends well for most of the characters, with the romantic couples, including Viola and Orsino, now correctly paired, and Viola and Sebastian reunited. High school readers will delight in the fun of Shakespeare’s comedy regarding these hapless lovers.
