With her father in prison...her brother and two nephews dead...and her sister-in-law missing for 3 1/2 years, Jennifer Graves had a grim story to tell.

This month it's come out in her new book, 'A Light in Dark Places.'

Graves brother was Josh Powell...her sister-in-law, Susal Powell.  In the book, Graves blames much of her family's tragedy on the negative influence of her father, Steve Powell.  He remains in a Washington state prison, for voyeurism.

In the book, Graves describes the controlling nature of Josh Powell.
