In Twelfth Night, Orsino loves Olivia.  Olivia loves Cesario.  Cesario is really Viola, who loves Orsino.  
The titles in the Graphic Shakespeare series are an ideal introduction to Shakespeare’s plays, but can equally well be used as revision aids.  

The main characters and key events are brought to life in the simplified story and dramatic pictures, and the short extracts from the original play focus on key speeches in Shakespeare’s language.

Each title is set out into acts in the same way as the original play, although the story is told in narrative text with only key speeches remaining in the original form. A portrait gallery of key characters provides and easy reference.
