Still grieving the loss of her mother, Eden visits Safina Island, her ancestral home, as a healing balm. But when she discovers an old sketchbook that belonged to her mother, she’s haunted by the images she sees drawn there. A creepy mansion covered with roots and leaves. A monstrous dog with dagger-sharp teeth. And a tall woman with wind-blown hair and long, sharp nails who is as beautiful as she is terrifying.

Days later, exploring the island alone, Eden follows a black cat through a rift in the bright day. She stumbles into Everdark, a parallel world where the sun never rises, where spirits linger between death and the afterlife, and where everything from her mother’s drawings is all too real—especially the Witch of Everdark, who wants to make Eden her eternal daughter. Can Eden find a way to defeat the witch’s magic? Or will she remain trapped in Everdark forever?
