SOMEONE IN THE ATTIC

A TikTok trend threatens a family’s sense of safety—and may be connected to a previous crime.

Most people are probably familiar with this urban legend: a babysitter receives creepy, threatening phone calls and later finds out they’re coming from inside the house. Mara offers a more complex, grown-up version of that legend here, updated to include TikTok and hidden cameras, but the sense of dread is similar: What would you do if someone seemed to be filming themselves inside your house? Julia has recently relocated with her family from California to Ireland to return to her roots and escape an unsavory incident involving her teenage daughter, Isla. She and her ex-husband, Gabe, are divorced but share custody and living space with the two kids in a luxurious gated community; when an anonymous user starts posting videos on TikTok that seem to show the inside of their house, Julia is spooked but figures it’s probably a really good fake. She’s got a lot on her mind, from Gabe’s secretive behavior to Isla’s teenage drama to the memories raised by her return. She and her three best friends grew up in this town, and it’s also where one of them, Donna, died tragically nearly 20 years ago. When another friend dies of what seems to be an accidental drowning just after Julia’s arrival in Ireland, Julia and her one remaining friend, Eleanor, are forced to confront the pain of the past as they look for clues to who is posting the increasingly alarming videos. Are the neighbors who they say they are? What happened to Donna’s socially awkward brother? Is Julia’s son telling the truth when he says there’s a man watching him at night? Mara skillfully layers red herrings and discoveries at a satisfying pace, sprinkled with a few flashbacks that lend even more insight into Julia as a tough and resilient character. The ending rushes a bit, offering a few too many neat bows to tie up all the threads, but it’s a minor complaint.

Well paced and creepy—especially if you’re alone in the house while you read.
