Query: Not her best work

I was very disappointed with this book. Danielle Steel's books seems to have less depth to them as each one is published. I didn't get totally involved in the book and want to learn more about the people in it as I usually do with her books. Usually, I don't want one of her books to end because I want to keep reading about the characters' lives, but this one didn't fall into that category! Of course, true Steel fans have to read all of her books no matter what! I do!
