Korean adoptee Emma Ricci has big plans. A graduate of New York's Fashion Institute of Technology, Emma dreams of starting her own fashion line and marrying her boyfriend, Adam. For now, she waits tables in a Korea Town restaurant.

When two masters of Chinese mysticism tell Emma she's the last in a long line of demon hunters, she assumes she's met two of New York City's crazier inhabitants. Her opinion changes quickly when she and Adam are targeted by wendigos, flesh-eating Native American demons. Emma survives the attack. Adam doesn't.

With the help of Chinese masters Li Bai and Zhan Ziquian, Emma discovers her heritage and past lives as a demon slayer. She also comes to the attention of Anthony DeAngelo, the NYPD detective assigned to the wendigo killings. DeAngelo obviously finds Emma attractive, but isn't going to let his feelings interfere with his investigation.

As demonic activity increases, it becomes apparent someone-or something-plans to open a hell-gate in Lower Manhattan. Emma's the only one capable of closing the door to the demon realm. Unfortunately, closing a gate kills the demon slayer.

Starting her own fashion line is beginning to look real unlikely...
