      Some people are capable of giving off the most efficient,
              effective glares when they are angry, even when they do not intend
              to glare so intensely.  This glare is a scary glare that
              gives another person pause, and makes them wonder if they are
              about to be harmed in some way.  This is most certainly not
              the intent of the bearer of the glare, but unfortunately, many
              people capable of glaring like this have an edge to their voices
              that match their glare when they are angry.  This just
              reinforces the recipient and/or observer of the glare that danger
              is imminent.
    
  
        Most people cannot just scare someone to death merely by glaring
              at them.  However, it seems that most people have a deathly
              and irrational fear of glaring or rather, being glared
              at.  This fear is intensified along with a distinct
              indignation if the glarer happens to be female.  Like Lestat,
              I am not really one to discuss gender issues all that much but
              it's unavoidable on the subject of an angry woman (especially
              since I am a woman and am well aware that no one wants to
              see a woman cry or get mad).  Again, the irrational fear of
              doom and danger intensifies if the glarer with the edgy voice is a
              woman.  It's as if, through her glare, she can and will
              actually kill...
      
      
    
    Fortunately for women like Rowan Mayfair, there are idiots who
          underestimate their potential victims.  They assume that a
          woman who is not very big, does not appear strong and has a
          countenance that appears to be incompatible with anger will make an
          easy target.  This guy wasn't counting on his victim being able
          to get mad, much less kill him. 
        
      
    
       
    
     
    
       
    
    
        
    
    
    In the Lives of the Mayfair Witches, there is a woman who does in
            fact have this ability.  All people have the power of
            anger - it is an extremely powerful emotion that affects the angry
            person and all those in their immediate vicinity.  People call
            it wrong because it can snake out from the person as an intense
            energy field, affecting the emotions of everyone around.  Rowan
            Mayfair calls it wrong because that energy field, when it comes from
            her, can literally kill a person.  Killing is wrong any way you
            view anger.
    
      
    
       
    
    
      
    
         
      
    
      
        
      
    
  
      We could say that anger is sometimes a woman's best defense
            mechanism.  It's what motivates her to protect herself and to
            respond to unjust treatment.  In certain situations, her anger
            itself is a defense.  As I said, no one wants to deal with an
            angry woman, especially one who has perfected the "death
            glare". 
    
    
      Rowan's ability to kill through her anger seems to be a literal
              metaphor for how we react to angry women.  Angry women are
              feared because angry women are assumed to have some power behind
              that anger that is evil, like murder.  The very fact that
              Rowan can kill through what Carlotta Mayfair called her "dangerous
              anger" could be a metaphor for the effect anger can have on
              another person unintentionally, even if the anger is
              well-justified. 
    
    
          And kill it has. 
          
        
    
              Rowan's anger at a playmate at school caused the death of the
                other little girl.  Her anger at a would-be rapist killed
                him before he could rape her.  The hurt from the betrayal
                of Graham Franklin provoked Rowan's anger, killing Graham in the
                kitchen of their home in Tiburon, CA.  But between Graham
                Franklin and the rapist were two other deaths, at least one of
                which Rowan was unaware of.
            
    
                First, there was a girl she got into an argument with in a
                    lab at UC Berkeley.  The girl apparently died during
                    the spring break.  Then, there was Dr. Karl Lemle, whom
                    Rowan became enraged with when she learned he was harvesting
                    aborted but live fetuses for research purposes.  And
                    after Graham Franklin, there was Graham's latest girlfriend,
                    Karen Garfield, who came to Rowan's house wanting something
                    of Graham's while Ellie Mayfair was dying inside the house.
                    Karen Garfield died about two weeks later.
                
      
  The interesting thing about the deaths of the girl in the lab, Dr.
          Lemle, and Karen Garfield is that Rowan was not actually present when
          they died.  This could be a metaphor for the power of anger
          lasting far beyond the actual moment of contact with the angry person,
          much in the same way a person's hurtful words are branded on one's
          memory for years to come, influencing their thoughts,
          feelings and beliefs even long after the speaker has
          died.  
  The people who died immediately as a result of being the subject of
          Rowan's anger probably received a more immediate and far more
          transfer of rage from Rowan.  Being attacked when it's clear that
          rape is the intent demands a defense.  Rowan's struggling would
          have been ineffective by itself but her anger stopped the
          attack.  For most women, an assertive, self-assured posturing
          with an alert, non-compliant demeanor tend to discourage would-be
          rapists because such a person is looking for a victim who will not be
          too much trouble. 
    Rowan's ability to kill through her rage has limits.  It is
            only capable of causing death in humans.  It was not capable of
            killing Lasher, who laughed at her attempts to kill him.  It
            was not capable of killing Lestat, who felt her conscious attempt to
            kill him as a push against his chest.  It was after this
            push that she begins to tell Lestat - through her mind to his - what
            that push was and what she almost did to Mona with it.
  
  
    Even if Rowan's rage could not kill a Taltos or a vampire, its
              force could be felt by them.  Both understood quickly what it
              was and that it came from her.  In both cases, Rowan used her
              telekinetic power intentionally when her other struggles with them
              failed.  Like any human, failure has a tendency to provoke
              anger and outrage, and Rowan Mayfair is no different.  Her
              ability to transfer her rage to the person she is enraged with
              could be considered a literal display of what we fear most about
              the anger and rage of other people - that it has the power to
              quite literally destroy us.
