There are many individuals who simply have a black heart. They hate everything and everyone.  They are horrible to deal with because they only love themselves.  It is what one might say a narcissist is.  They do not care about anything or anyone but themselves.  Anyone who has ever dealt with that type of person clearly understands.  Originally, I thought a narcissist was someone who was full of themselves.  That is not really the case.  There are actually websites describing these black heart types of people.  They are almost identical in their actions and the words they use.  It is literally shocking the first time you read it.  It is almost as if the writer was in the room when you were dealing with a narcissist.  They state their phraseology word for word.  In the olden days, a black heart usually referred to an evil knight.  Just because knights don’t exist any more doesn’t mean that that type of person has disappeared.  One of the interesting things about a person with a black heart is that they are controlling and really don’t care who they hurt.  It is their way or they will fight hard to get it their way.  Even if it means hurting innocent children, it just doesn’t seem to matter to them.  Is a mental issue?  Probably, or possibly they grew up without love and it made them become whom they are as adults.  Can you change these individuals?  Not according to the websites.  It’s almost as if once their hearts turn and they are narcissists, there is no turning back.  The best thing you can do is that if you find out too late that your partner has a black heart and is a narcissist is to leave.  The relationship will destroy you in every way.  Their revenge to break you is overwhelming.  In the Good Gus series, no one had a black heart.  Bad Bart wasn’t nice, but Sheriff Gus turned him around.  The series is available exclusively online and with Kindle worldwide.  If you are dealing with a relative who has a black heart, disown them.  I hope you will consider as one of your summer reading books “Misplaced Trust.”  It is available on 24 Symbols, Apple, Nook, Kindle, Kobo, Page Foundry, Scribd, Playster and Tolino.
