Darkness blooms in bestselling author Kalynn Bayron's new contemporary fantasy about a girl with a unique and deadly power. Briseis has a gift: she can grow plants from tiny seeds to rich blooms with a single touch. When Briseis' aunt dies and wills her a dilapidated estate in rural New York, Bri and her parents decide to leave Brooklyn behind for the summer. Hopefully there, surrounded by plants and flowers, Bri will finally learn to control her gift. But their new home is sinister in ways they could never have imagined—it comes with a specific set of instructions, an old-school apothecary, and a walled garden filled with the deadliest botanicals in the world that can only be entered by those who share Bri's unique family lineage. When strangers begin to arrive on their doorstep, asking for tinctures and elixirs, Bri learns she has a surprising talent for creating them. One of the visitors is Marie, a mysterious young woman who Bri befriends, only to find that Marie is keeping dark secrets about the history of the estate and its surrounding community. There is more to Bri's sudden inheritance than she could have imagined, and she is determined to uncover it . . . until a nefarious group comes after her in search of a rare and dangerous immortality elixir. Up against a centuries-old curse and the deadliest plant on earth, Bri must harness her gift to protect herself and her family. From the bestselling author of Cinderella Is Dead comes another inspiring and deeply compelling story about a young woman with the power to conquer the dark forces descending around her.

How much would you risk to save the ones you love? Would you tempt even the most dangerous fate? Briseis has one chance to save her mother, but she'll need to do the impossible: find the last fragment of the deadly Absyrtus Heart. If she is to locate the missing piece, she must turn to the blood relatives she's never known, learn about their secret powers, and take her place in their ancient lineage. Briseis is not the only one who wants the Heart, and her enemies will stop at nothing to fulfill their own ruthless plans. The fates tell of a truly dangerous journey, one that could end in more heartache, more death. Bolstered by the sisterhood of ancient magic, can Briseis harness her power to save the people she loves most?
