The two are kidnapped to Nightfall Gardens, the family’s ancestral home, a place shrouded in ancient mystery, where they meet their dying grandmother and learn of an age-old curse placed on Blackwood females.
Lily must take over as protector of the house and three haunted gardens that hold mythical beasts, fairy-tale nightmares and far worse. If she doesn’t, the evil trapped there will be unleashed and bring on a new dark age.
While she deals with malevolent ghosts inside the house, Silas is put to work in the gardens, where one wrong step means death.
Along the way, they search to unlock the secrets of the house and to stop the creatures in the gardens before time runs out and the world is destroyed.
