What are some good points to consider when writing an essay about the play "The Skriker"?

At its core, this difficult text is a story of love, loss,
and revenge. If your assignment is fairly open as far as topics go, I encourage you to
brainstorm ideas revolving around one or more of the above subjects and to come up with
a theme statement.  In order to accomplish this, you must ask, "Through events, details,
and techniques used in this play, what is the author trying to say about one (or more)
of the subjects above?  What message is he trying to get
across?"

In order to answer this question, you must look
specifically at the events, details, and techniques used in the play and how they work
to create the author's message.  Brainstorm a list of ideas/examples, then organize your
examples into logical categories.  Once you come up with a theme statement (which can be
used as the thesis for your essay), prove it by providing examples in an organized
fashion (which are your sub-topics).

To help you get
started with some "good points" to consider, I offer the following. 
Consider...

• the idea of teen-aged mothers as two
  of the main characters.


• the use of an evil "fairy"
  character who is able to change forms in order to seduce, manipulate, and
  entrap.


• the use of language: The Skriker's prose as
  compared to the modern English dialogue of the two
  girls.


• the elements of horror: psychosis, possession,
  magic, and the supernatural.
