From the publisher: "In this provocative meditation on new motherhood—Shirley Jackson meets The Awakening—a postpartum woman’s psychological unraveling becomes intertwined with the ghostly appearance of children’s book writer Margaret Wise Brown. There’s a madwoman upstairs, and only Megan Weiler can see her. Ravaged and sore from giving birth to her first child, Megan is mostly raising her newborn alone while her husband travels for work. Physically exhausted and mentally drained, she’s also wracked with guilt over her unfinished dissertation—a thesis on mid-century children’s literature. Enter a new upstairs neighbor: the ghost of quixotic children’s book writer Margaret Wise Brown—author of the beloved classic Goodnight Moon—whose existence no one else will acknowledge. It seems Margaret has unfinished business with her former lover, the once-famous socialite and actress Michael Strange, and is determined to draw Megan into the fray. As Michael joins the haunting, Megan finds herself caught in the wake of a supernatural power struggle—and until she can find a way to quiet these spirits, she and her newborn daughter are in terrible danger."

When an ambitious young violinist makes a deal with the devil in a Venetian canal, she can’t possibly foresee the consequences of getting exactly what she wants. The author calls her third novel a “baroque Venetian fairytale about two young female music students and their all-consuming hold on one another,” with jealousy, Vivaldi, and ghostly lagoons. Or for a punchier version: her “Faustian Little Mermaid fever dream.” A lushly rendered tale of dark fantasy, art and ambition, forbidden love, and a love letter to Venice and its history. For fans of V. E. Schwab’s The Invisible Life of Addie LaRue and Silvia Moreno-Garcia’s Mexican Gothic.
