Down Among the Dead Men - Robert Gregory Browne

The Day of the Dead - El Dia de los Muertos - is when Mexico celebrates its lost loved ones. But for two people brought together by the realization that a sinister cult is at work, it's not a time to celebrate. Disgraced journalist turned true crime writer, Nick Vargas, is determined to seek the truth behind the slaughter of seven nuns in a derelict house near the Texas border. His quest leads him to Hannah Freeman, a prosecuting attorney whose sister, Jen, mysteriously vanished while they were on holiday together in Ensenada. It becomes clear that there is a link between the murders and Jen's disappearance, and their quest for the truth and their hunt for Jen leads Hannah and Vargas to house in a small town in Mexico. The House of the Dead, known for its dark secrets and deadly rituals. Someone - or something - sinister awaits them - lurking in the shadows. Watching them. Waiting for the right moment to strike.
