On her 23rd birthday, Nadia Winters receives a mysterious gift that throws her into a magical world of the supernatural, witchcraft, and cutting-edge technology in Silicon Valley. 

Living her life as an unsuspecting human, Nadia never imagined that a world of supernatural and otherworldly creatures existed until her powers were revealed by this piece of magic-filled tech. Once worn, a decades-old spell is shattered, one that was cast to keep Nadia safely hidden from the Blood Oath that binds her family to vampire business mogul, Mercurio.

With her identity exposed, and a demon bounty hunter pressing her to fulfill her ancestral obligation, Nadia now faces an impossible choice: give up her powers as a witch and go back to a normal life or agree to serve her vampire overlord.

Tricked into bending to Mercurio's will, Nadia agrees to move to San Francisco where she must infiltrate Myst, a startup that hides magic in plain sight behind the latest technology. Her mission is to pass along insider information to the powerful vampire, but as she grows closer to the CEO, Rune, Nadia struggles to decide once and for all where her loyalties lie.

As the danger mounts, and with the chance that her true intentions could be exposed at any moment, will Nadia betray the handsome and enigmatic CEO and her new friends, or will she manage to escape the Blood Oath that binds her to Mercurio?
