The Demon’s Spawn, by Christine Triner

Some bloodlines are not inherited. They are hunted.

Salem, 1693: as witch-hunt hysteria tightens its grip, a young wife named Elspeth becomes the target of something far older than fear. Marked by a demon’s vengeance and condemned by the town that should have protected her, she dies carrying a curse that refuses to burn with her.

Three hundred years later, twin girls are born in London—and immediately torn apart. Eliza is raised in love, protected from the truth of her origins. Eloise grows up unwanted, watched over by a darkness that whispers, encourages, and waits. Though separated by an ocean, the sisters remain bound by a brutal psychic connection: every act of violence Eloise commits tears through Eliza, body and soul.

As Eliza follows the trail to Salem, she discovers that some monsters are made, some are born—and some are family.
