Wow! You really like V.C. Andrews!  Can you tell me more about your favorite books and characters?
Flowers in the attic was V.C. Andrews first book.  It was such a good book that they made a movie based on the novel.  The movie was not quite as good as the book.
The Dollanganger children are much beloved!  Which child is most like you and why?
Your are familiar with the Dollangager children!  That's awesome!  I feel I am most like Cathy, she was the oldest and the mother figure to the twins.
So, were you also married thrice or, is that where the similarities end?  Did you grow up caring for your younger siblings like Catherine?
Like Cathy, I was the oldest in my family.  I was able to relate to Cathy well because I took care of my younger siblings.  At times, I felt like a mother as well.  Love has no boundaries.
Definitely, it's amazing how books have the ability to articulate feelings we have always known. I found the relationship with Chris to be a bit too salacious for me.  What do you think about it? 
That is so true.  I completely agree with you regarding Chris and Cathy's relationship.  All they had was each other and the twins locked in the attic.  Who am I to judge? 
What is your take on the setting of the book as a character and what do you think it represents?
Flowers in the attic was an extremely heart breaking novel.  Flowers represented the children being locked up in the attic.  They were small innocent children left alone, confined in the attic with no human interaction but their own.   
They are very deep themes to explore to be sure.  What book in the series to you love best after Flowers in the Attic?
After Flowers in the attic was Petals on the wind, If there be thorns, Seeds of yesterday, and Gardens of Shadows.  They were all equally good however If there be thorns is also one of my favorites from the series.  It was the 3rd book from the series.   This is when Cathy starts her career in ballet.
