In life, Dakota Donovan has always had two options; to run, or to fight.. and she's been running. She's been able to see mysterious visions of figures that no one else can see for as long as she could remember, and when the visions lead her to meet Blaine Garenster who has a curse on his heart, Kota is determined to make him feel something for the first time... but that comes with a price, and she soon learns that in death there is only one option, and it's to fight..
Swept into a world of demons, reapers, half-breeds and angels, Kota must find a way to escape the dimension of Ruppell, a place where the inhabitants are anything but human, all the meanwhile having the one person who can help her have an inability to feel any compassion or love.
Kota's only chance of survival lies within Blaine, but in order to save her, he must find a way to feel emotions and learn how to deal with them. With more than one kind of monster after them, the pair struggle to defeat the forces of death and return Kota back to her normal life.
