Blue Bloods by Melissa de la Cruz

Summary: When the Mayflower set sail in 1620, it carried on board the men and women who would shape America: Miles Standish; John Alden; Constance Hopkins. But some among the Pilgrims were not pure of heart; they were not escaping religious persecution. Indeed, they were not even human. They were vampires.The vampires assimilated quickly into the New World. Rising to levels of enormous power, wealth, and influence, they were the celebrated blue bloods of American society.

The Blue Bloods vowed that their immortal status would remain a closely guarded secret. And they kept that secret for centuries. But now, in New York City, the secret is seeping out. Schuyler Van Alen is a sophomore at a prestigious private school. She prefers baggy, vintage clothes instead of the Prada and pearls worn by her classmates, and she lives with her reclusive grandmother in a dilapated mansion. Schuyler is a loner...and happy that way. Suddenly, when she turns fifteen, there is a visible mosaic of blue veins on her arm. She starts to crave raw food and she is having flashbacks to ancient times. Then a popular girl from her school is found dead... drained of all her blood. Schuyler doesn't know what to think, but she wants to find out the secrets the Blue Bloods are keeping. But is she herself in danger?

I loved that the Blue Bloods are supposed to be fallen angels and they are immortal until they prove that they are worthy to go back to heaven. I also really liked how Melissa de la Cruz followed the story in true American history, it made it seem that it could be real.
