Ash Season: 5

Every house has a foundation. And every foundation has a secret buried in it.Fire investigator Gemma Pryor has spent her life studying the ashes of other people's tragedies, running from her own. Twenty-seven years ago, her father confessed to burning down a vacant vacation home in upstate New York and was sentenced to twenty-five to life. He never appealed. He never explained.Gemma accepted the official story, until a construction crew breaks ground on the old property and unearths a fireproof lockbox sealed into the concrete foundation. The box contains three things: a marriage license, the dental records of a woman Gemma has never heard of, and a note in her father's handwriting.As Gemma applies her forensic expertise to the decades-old arson, she discovers a chilling truth: the house wasn't empty, and the fire wasn't a simple act of revenge. Her father's confession wasn't an admission of guilt-it was a shield to protect the real arsonist. Forced to interrogate the people she loves most, Gemma must decide whether to leave the past in the ashes or burn her own family to the ground to expose a murder that no one was ever charged with.
