Any other books out there that are as good as Flowers in the attic? - flowers in the attic syndrome

I loved this book and the series of the same. I read a book as exciting and frightening, as it was ... if you know what I mean. I read a book that's like in real life, like flowers in the attic .... Does anyone know of?
