As an environmental studies major, Allie knows the planet is in trouble - a series of natural disasters recently rocked the northern hemisphere, and species across the globe are going extinct. What Allie doesn't know is that her world's decline is a result of an ancient battle called the Night War - the Norse goddess Nott's crusade to control the weakest of the light realms. And Allie most definitely doesn't know that her existence is the only thing stopping Nott from dragging the earth into total darkness.

Maddison James is about to discover some truths about the world. Firstly...supernaturals exist. WTF? Secondly...she is one, even though no one seems to know exactly what kind. Double WTF. Thirdly...she’s about to go back to school. Well, things just got a little more interesting. The Supernatural Academy is where shifters, vampires, magic users, and fey are educated. Where they are taught about their abilities, and how to function in the human world. Maddison already has the human part down, but this supernatural thing is an entirely new dangerous game.

The Red Queen has stood for a century, and her power is beyond reckoning. Or so Arianna believes, right up until the final tolling of the bells. The queen has fallen. Four heirs will now fight it out for the crown.
