Sisters in My Books

  If you have read any of my books, mainly book 1 and A Second Chance at Love, you may wonder why I  always have sisters in my books. Both my heroines didn't know about a sister (although Marge had one before she discovered Samantha.) They didn't come looking for them either, but their sisters found them.
In The Past Hunter, Julie found that the new manager of  Books and Gifts is her biological sister. Her parents couldn't afford to keep her, but they never told Julie about her...and Julie never asked. In A Second Chance at Love, Marge found that a woman came to help Marge elude the villain was her half sister. Marge's father sired her when he was in the military. Samantha had been born out of wedlock. When Samantha's mother was on her deathbed, she asked to know her real father was so that for medical reasons, she could have his records. 
Even in my upcoming book, the story takes places when the two sisters founds out the truth about their mother's origin. So why sisters? Why not brothers?
Perhaps the answers lies in the fact that I never had a brother. When I was younger, I wanted a little brother, but my parents stopped at me. Growing up, we didn't have much a social life and our parents sheltered my sister and me. We had one friend in common and other friends came and go, but my sister and I became friends knitted through our circumstances. We were each other's best friends because we there for each other.  I think having a sister is having a sister is a great thing. What about you? Do you have siblings? Or are you like Beth in my series or Darlene in purify My Heart when you are the only child?
