A dark, seductive tale of hunger, love, and transformation from the bestselling author of The Death of Jane Lawrence.

The only thing more terrifying than a brood's hunger . . . is its mother's.

Beatrice is a broodmother: a vampire responsible for nursing newly made fledglings through the first years of their unlife. She nests in an abandoned, isolated warren of office space beneath her patron's skyscraper, where she raises her fledglings—two difficult, hungry children of the night.

But when she takes on a third, the balance ruptures. Her hunger swells beyond control. Her body alters, betraying its purpose, transforming her into something even more monstrous.

Desperate to master herself once more, Beatrice courts a mortal OBGYN who might be able to unravel the secrets of her unnatural anatomy. But soon their connection threatens the secrecy of her vampiric coven as well as the safety and development of her dependent nurslings… and in a world governed by secrecy, even the smallest revelation could prove fatal.
