"Instagram-famous triplets Cecily, Amber, and Rudy--the children of home renovation superstars--are ready for a perfect summer. They're on track to reach one million followers with a few carefully crafted posts, and they've just moved onto the site of their parents' latest renovation project: a three-million dollar McMansion in Upstate New York. Just hours into the move, the Cole triplets begin to receive spine-tingling messages from someone from a follower. It soon becomes clear that this anonymous threat is more than a simple Internet troll, and the follower can't wait to shatter the Cole family's perfect veneer and take back what's theirs. As the eerie warnings manifest into deadly "accidents," the Coles begin to look into the history of the house--and the chilling secrets they uncover are far more than they bargained for."--dust jacket.
