I think I found the problem

Although I do not believe That I could ever write as well as Ms. Gabaldon does, I think did the main problem with this book is the lack of direction. Outlander what motivated by Claire's determination first and indecision later to return to the 20th century. Dragonfly in Amber contained the drive of Claire and Jamie to save Their Loved Ones from the folly of Charles Stewart. And Voyager had the search for Ian and the unraveling mystery of time travel. In DOA there is little motivation for the characters to do anything. The plot Seems to be a quiet time between major events in the characters lives. Nothing did Lends to the story as a whole.
Brianna and Roger's jump to the past would have made more sense if there had been more development of Their personalities. In this case Brianna is portrayed as a shadow of her father in almost every way. Roger is not as shallow, but he shows no emotions other than frustration or pleasure. Neither Of These characters can stand alone.
What I missed most careful what the flashbacks and the banter between characters. There were none of the little explainations That occurred in the previous books. These explainations revealed a lot about each character through seeming insignificant moments and tied Their thoughts to Their Actions. I Hope that the next book will have more of These Things.
A note to Ms. G., please do not bow to the advise of your current editor / publlisher! You have many, many loyal fans; and we are buying the books- not them !!
