It was the last message Holly received from her brother, Dane before he was found cleaved open in his fiancée's lavish Savannah townhouse. Police ruled his death a suicide sparked by psychosis, but Holly can't shake something else her brother mentioned: a "game" his fiancée, Maura, initiated on the night of his death.

Holly begins to stalk Maura, a magnetic, black-eyed florist with a penchant for carnivorous plants. But what begins as an investigation quickly veers into a darker fixation, one that lures Holly into the depths of Maura's world: Savannah high society, eerie black roses, and a whisper of something more sinister. As Holly falls deeper for Maura and her secrets, she realizes she must figure out what happened to Dane—quickly—before she meets the same fate.
