Nestlings is Another Gripping Journey into Terror from Nat Cassidy

With his breakthrough horror novel, Mary: An Awakening of Terror, Nat Cassidy revealed himself to be a writer adept at balancing the slow burn of dread with moments of sudden, sheer terror. That novel, the story of a woman who slowly uncovers the truth about her own dark roots and frightening nature, is all about a search for something, and Cassidy milks the suspense of that search for all it’s worth, delivering an unforgettable horror experience. With his latest book, Nestlings, he’s done it again, in a completely different and utterly haunting way, delivering another must-read from one of horror’s brightest rising stars.
Reid and Ana, a young couple with a new baby and almost a year of bad luck behind them, are finally catching a break as the novel opens. They’ve just won an apartment lottery for a new home at The Deptford, one of New York City’s most historic, elegant, and exclusive residential buildings. People like Ana and Reid can’t afford The Deptford under normal circumstances, so getting a place inside its legendary walls feels like a much-needed win. Or at least, that’s the way it should feel. While Reid is loving their new home, throwing himself into exploring and examining every nook and cranny of its decades-long history, Ana isn’t so sure about the Deptford, and not just because it’s somewhat tricky to navigate the building and its grounds in her wheelchair. No, something else is going on in this stately old residence, something that’s got both Ana and her daughter Charlie on edge. The Deptford, it seems, didn’t just want them because they won an apartment lottery. The Deptford wants something else, something the fledgling family never saw coming.
Just as Cassidy pitched Mary as a novel that reads like Carrie if the title character were a middle-aged woman in crisis, he’s clearly angling for a take on Rosemary’s Baby with Nestlings. There are clear echoes, right from the beginning, of the too-good-to-be-true deal present in Ira Levin’s classic supernatural thriller, but Cassidy is not content to riff on a story we all know. Knowing winks and nods aside, Nestlings quickly throws itself into forming dark shapes all its own, and that begins with the deft way Cassidy handles not one, but two characters on a journey of discovery.
