When Izzy is dragged from New York City to a tiny town for her parents' new job, the only silver lining is the gorgeous old mansion they moved into. It is the former home of an artist's muse who died tragically in a fire. The house has its quirks: whole floors closed off, paintings covered up, and cell reception nonexistent. Izzy throws herself into starting an Instagram fashion account using the gowns and jewelry she finds in the house. The pictures go viral, and soon she has a new best friend, a potential boyfriend, and fangirls who want the photo-shoots and fame for themselves. But there's a darkness in the house, and a darkness growing in Izzy, too. When girls start dying, something in the house is growing in power, with deadly intentions.
