The chilling horror debut from a #1 international bestselling author—an art conservator’s obsession with a mysterious painting spirals into a nightmarish descent, where the line between reality and the supernatural shatters, threatening both her sanity and her life

Mathilde "Tilly" Crewson, a thirty-nine-year-old mother and art conservator, is tasked with restoring The Mother. The painting, believed to be the work of a female surgeon-turned-artist after a personal tragedy, is the rumored fourth piece in a collection of only three known works. But this newly discovered painting, scarred by fire, holds more than meets the eye.

Soon after receiving the painting, Tilly discovers she’s unexpectedly pregnant, and strange, inexplicable occurrences begin: terrifying insect swarms, eerie visits from her long-deceased mother, and sinister whispers that invade her mind. As these malevolent forces intensify, Tilly comes to a harrowing realization: the only way to sever the perilous bond she shares with the painting is to destroy it. But The Mother has plans of her own—and they’re darker than Tilly could ever imagine. . . .
