When eighteen-year-old Jenny O'Brien falls down a manhole and dies, her family and friends mourn her untimely death. However, Jenny wakes up in a small haven called Strangely and it is as if she has always been here.
In Strangely, she and three other girls, Emily, Abby, and Zara live in a crooked little house on a slight hill, with a view of clouds in every direction they look. Everything is normal until they read the Book of Eudemon. When the four girls use their combined powers to escape Strangely, they arrive in The OtherWorld, the upside-down of New York where they meet Gorgon and the others.
Gorgon leads a band of angels who had been murdered, whose bones are hidden beneath a house in an affluent suburb, and before they are dragged to Hell, their bones must be found and properly buried but time is running out very quickly.
Before being banished from Strangely, Gorgon foretold of four girls who will have powers to rid the world of demons but sometimes demons are only human.
