Hi JJ, here's the synopsis of GRAVE SECRET taken from back jacket:

Twenty-one-year-old Claire Bannister has just been released from a Florida mental hospital, where she spent over three years on the forensics unit for arson and murder-crimes to which she pled "not guilty by reason of insanity." The trouble is, Claire's innocent. She knows who really set the house fire that killed her siblings on that balmy night in Pensacola, but she can't tell. And she knows that her stepmother and lifelong nemesis, Sisley, will be watching her every move. Sisley never believed that Claire set the fire that killed her children, and now Sisley will stop at nothing to get to the truth. Claire flees to Tampa, unaware that Sisley is having her followed. Claire is on a mission to find her boyfriend, Billy Powers, who disappeared the night of the fire with a briefcase full of cash extorted from Claire's powerful father, Judge Oren Bannister. Will Billy still have in his possession the one item that Claire must get back from him? Confronted by one dead end after another, Claire finally marries Richard Quenell, a handsome and wealthy attorney with a few secrets of his own. Claire conceals her past from her new husband, a decision that has disastrous results. When Claire, Sisley, Billy and Richard finally square off, the consequences will be devastating, and Claire will be faced with a decision that could change her life-again.

My sister posted a review on Amazon about the book which gives some clues about the true parts.

The new book will be about writing and how to generate unlimited creativity. It's sort of a sequel/companion book to Time to Write. It should be out in mid 09.
