Rosewood's Ashes by Aileen Schumacher is the forth book featuring Tory Travers and David Alvarez. I have not read the previous three titles. Tory has to confront her past when she learns that her father, who she hasn't seen in years, is in a coma from an automobile accident. So she and her partner David Alvarez fly to her hometown of Gainesville, FL. This book alternates between present day and events that happened 1923 when a white mob attacked a black town of Rosewood, Florida. A series of murders seem to tie the present day to this event 70 years before. The clues are in the past but will they discover it before Tory becomes another victim.
