The Family Plot by Megan Collins

Exceedingly entertaining. -The New York Times Umbrella Academy meets Tana French. Dark, claustrophobic, and beautifully written. -Andrea Bartz, author of We Were Never Here From the author of The Winter Sister and Behind the Red Door, a family obsessed with true crime gathers to bury their patriarch-only to find another body already in his grave. At twenty-six, Dahlia Lighthouse is haunted by her upbringing. Raised in a secluded island mansion deep in the woods and kept isolated by her true crime-obsessed parents, she is unable to move beyond the disappearance of her twin brother, Andy, when they were sixteen. After several years away and following her father's death, Dahlia returns to the house, where the family makes a gruesome discovery: buried in their father's plot is another body-Andy's, his skull split open with an ax. Dahlia is quick to blame Andy's murder on the serial killer who terrorized the island for decades, while the rest of her family reacts to the revelation in unsettling ways.
