This book is in Andrew's usual style of writing about children who have parental issues, in this case cruelty by the grandparents. I found the book quite similar to her other books such as Flowers in the Attic and The Unwelcomed Child. This installment of this series is about the diary of Christopher Dollanganger.
The book didn't really offer any more insight to the overall plot than the previous books. It didn't even get to the end of the diary while obviously setting itself up for a sequel.
My thoughts on The Unwelcomed Child were the story has become a formula, albeit a successful formula for the pseudo Andrews. This book, too, is far too similar to past books in style and characterizations without the flair and personality of the original V.C. Andrews. I'm not sure the reincarnation is working.
It was not as good as the two previous books.
This book may have been received free of charge from a publisher or a publicist. That will NEVER have a bearing on my recommendations.
