Lizzie Headrick thought she'd finally met her prince charming in Dr. Grant Chatsworth. Their fairytale courtship swept her off her feet and ended with the engagement ring of her dreams. As she moves into one of Buckhead's finest estates, Lizzie soon learns all that glitters is not gold. Her handsome husband, a renowned cardiac surgeon and the developer of a new congestive heart failure drug, is becoming cruel and controlling. It isn't long before she finds herself captive in the vast expanse of his estate without a phone or car and under the watchful eye of Flossie who runs the household. When Lizzie discovers that Cardiac Care Research, his drug development company, is a Ponzi scheme, she realizes her life could be in danger if she doesn't escape the gated mansion on the hill. Her only hope is to get to Biloxi, Mississippi, and seek refuge with her sister, Maggie. Maggie and her husband, Leland, quickly find a safe harbor for Lizzie at a house on the bayou. However, the house at the end of the street might not be the quiet retreat Lizzie was hoping for. The confines of her hideaway begin to close in on her, so she retreats to the historical cemetery next door where a small, damaged tombstone of a child soon catches her eye and captures her heart. Just as Lizzie Chatsworth thinks her world can't get any more complicated, she finds herself in the middle of a mystery from the 1800s that pulls her in, demanding that she seek justice. As her husband's empire begins to crack and crumble, he's more determined than ever to find Lizzie and eliminate her. But, will the mystery of the small tombstone end Lizzie's life first?
