Complete Tempest [EPUB ebook] 
An Annotated Edition of the Shakespeare Play

In only two plays The Comedy of Errors and The Tempest–does Shakespeare observe the unities of time, action, and place. While these apparent constraints seem to restrict the playwright, they also demonstrate an artistry that transcends the apparent restrictions, especially in The Tempest. The added themes of justice satisfied and of young love realized make for a satisfying blend of artistry and stagecraft.
