Plot Summaries
 

Schuyler Van Alen never fit in at Duchesne, her prestigious private school, preferring grungy second-hand clothes to expensive designer labels, and living in a decrepit old mansion with her grandmother, Cordelia, the only family she has. While most find her strange, she is content with her life and her two only friends, Oliver Hazard-Perry and Dylan Ward.

But when Schuyler turns fifteen, her life suddenly begins to change. Aggie Carondolet, a Duchesne classmate and close friend to Schuyler’s nemesis, Mimi Force, is found dead in one of the city’s nightclubs, she notices mysterious, intricate blue veins pulsing from her arms, she craves eating raw meat, and Jack Force, a dashing and popular boy who happens to be Mimi’s twin brother, begins to take a sudden interest in her.

She receives a letter telling her that she has been accepted into “The Committee,” and although she’s not sure she wants to attend, she agrees due to the insistence of her grandmother. When she arrives, she finds that she has more in common with her classmates than she thought. She is a Blue Blood—a vampire. A society of powerful and influential Americans whose ancestors can be traced back for centuries. Schuyler and Oliver, whom she learns is also her human Conduit, are suddenly thrown into a race to find the answers to the questions that she, and everyone else is asking. Have their ancient enemies, the Silver Bloods—vampires who prey on vampires—suddenly returned after having thought to be vanquished? Is the incriminatory circumstance of Schuyler’s birth that broke the most sacred code of vampires the reason why her mother has been trapped in a coma for so many years?

After a tragic attack involving Cordelia, Schuyler soon finds that she herself is in danger, and that she has a long journey ahead of her that will take her to every corner of the world.
