For fans of The Invisible Life of Addie LaRue, an inventive and romantic speculative novel about two women—a witch and an immortal demon—who make a Faustian bargain and are drawn into a cat-and-mouse chase across multiple lifetimes.

Beginning in the 16th Century in Suffolk, Cybil Harding is a First Daughter. Cursed to bring disaster to those around her, she is trapped in a house with a mother paralyzed by grief and a father willing to sacrifice everything in pursuit of magic.

Miriam Richter is a creature of shadow. Forged by the dark arts many years ago, she is doomed to exist for eternity and destined to be alone—killing mortals and consuming their souls for sustenance. Everything changes when she meets Cybil, whose soul shines with a light so bright, she must claim it for herself. She offers a bargain: she will grant Cybil reincarnation in exchange for her soul.

Thus begins a dance across centuries as Miriam seeks Cybil in every lifetime to claim her prize. Cybil isn’t inclined to play by the rules, but when it becomes clear that Miriam holds the key to breaking her family curse, Cybil finds that—for the first time in her many lives—she might have the upper hand. As they circle each other, drawn together inescapably as light and dark, the bond forged between them grows stronger. In their battle for dominance, only one of them can win—but perhaps they can’t survive without each other.

Natasha Siegel’s fantasy debut is full of transporting historical detail, with thrilling twists and an abiding, thought-provoking romance that feels at once epic and deeply personal. Ambitious, gothic, and magical, As Many Souls as Stars is about the lengths we go to protect ourselves, our legacy, and those we love.
