Burnback by Wren Bishop

State Fire Investigator Nora Altman doesn't miss evidence. Haunted by a past mistake, she arrives in rural Hardin County to investigate a string of unsolved arsons. Her primary suspect? Judge Caldwell, a brooding, fiercely protective local welder with scarred hands and dark family secrets. As Nora digs through the ash of a twenty-year conspiracy, she realizes the fires are just the surface. Someone is using the flames to cover up a murder—and Judge’s missing sister might be the key to it all. In a town built on silence, discovering the truth might burn them both to the ground, or forge a dangerous, undeniable bond. Some fires destroy. Others refine.
