June James is a thief of magic.

It’s been two years since the fae descended onto the mortal world and carved a piece of it for themselves. No one knows why they did it, but now there is a Line in New York City, and beyond it the streets abruptly give way to the realm of magic.

Seventeen-year-old June is thrilled when wounded fae appear on the doorstep of the veterinary clinic where she works. Sick of living in the shadow of her successful sister, June secretly saves the creatures that most humans hate and fear. When a fae succumbs to its injuries, she discovers the source of its magic hidden in its body. Consuming magic is usually fatal to mortals, but for lonely, ordinary June, the temptation is too great.

She doesn’t die. Instead, magic imbues her with temporary, addictive bursts of power – and quickly starts to strip her of her humanity. Craving more, she impulsively kills another injured fae for its power, and not even her immediate regret can stop the fae from sending a monstrous nightmare to collect her for judgment.

June flees the human side of the city and crosses the Line, where the streets are an overgrown urban wasteland and humans hide in isolated camps. A wanted murderer stranded in a world not her own, June encounters other lost souls: a skinny, tattooed human hunter desperately attempting to be a hero; her own doppelganger, a sickly clone whose very life is tied to June’s humanity; an abandoned child zombie trapped in a rotting body; and a strange man with white eyes, a soldier to whom doing the right thing means betraying everyone he loves.

A war is brimming on the horizon, and June and her stolen magic have a terrible part to play. As she struggles to escape the consequences of her past, June finds a family, redemption, and the strength to defend her fellow monsters when a force worse than the fae threatens the entire world.
