Teenaged Briseis, who possesses a supernatural power over plants, including poisonous ones, inherits a dilapidated estate in rural New York and must protect herself and her family from centuries-old secrets that threaten their lives.
When Briseis's aunt dies and wills her a dilapidated estate in rural New York, Bri and her parents leave Brooklyn behind for the summer. Hopefully there, surrounded by plants and flowers, Bri will finally learn to control her gift: the ability to grow plants from tiny seeds to rich blooms with a single touch. Their new home 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. Then strangers begin to arrive on their doorstep, asking for tinctures and elixirs. One of the visitors, Marie, is keeping dark secrets about the history of the estate and the surrounding community. -- adapted from jacket
