Query: Characters are all the same

I have been a huge Garwood fan since I read The Gift, but I am really disappointed with the last few books. All of the characters, especially the females, are exactly the same. They only have one personality. For the Roses was my first disappointment with Garwood and I've been similarly disappointed with the rest of the roses series. She needs to seriously work on character development before her next book.
