Query Letter

I have written the same novel six times now.  I have edited, re-edited and edited again. 

 The title has changed three times,  the main character has had different personalities.  

The Story Line has changed (to a point). 

The Point of View has changed.  

Some Characters have gotten news names and the writing has changed.  

But most of all. . . I have changed.  

I now know how Not to write this novel.  

I know my characters better than I know myself.  

I can name each character, their age and describe every one of them to you. 

I can say without a doubt that my writing has improved. 

My style is more clear.

I have learned a lot, gained many friends,

earned respect,  created a blog that people (aside from my family) read.

I have become a part of an amazing team (The A to Z team, of course) 

And I go to Writing Conference yearly.  

And yet,  after six years. . . I have still never written a Query letter.  I am terrified!  (No I am still not done with the book.)

But I know it is time to start working on the query letter.  

I have always been told that you should put just as much work into the Query letter as you do your book.  I used to think 'I have to work on the query letter for six years too?  I thought working on the same novel that long was hard!'

I now know that this is not what people meant.  Putting the same amount of work into it is not the same as taking as long to write it.  

But. . . I don't know where to begin.  So Suggestions?

Where did you look for help in writing your first query letter?
