One of the most romantic of Shakespeare's plays, Twelfth Night, or What You Will is thought to have been written around 1601-1602 as an entertainment for the end of the Christmas season.

In a classic tale of mistaken identities, twins Viola and Sebastian are separated after their ship founders on the coast of Ilyria. Disguising herself as a boy, Viola falls in love with the Duke Orsino, who loves the Countess Olivia. When she meets Viola, Countess Olivia falls for her, believing her to be Cesario. It contains some of Shakespeare's most beautiful poetry including Orsino's speech that begins, 'If music be the food of love play on'.

As well as the play itself, this edition contains:

• An extended introduction that looks at the play's history, its structure, and characters
• A glossary of words and terms
• Notes on the text
• A timeline of William Shakespeare's life and work
