Masquerade by Melissa de la Cruz

Summary: Schuyler Van Alen wants an explanation for the mysterious deaths of young vampires. With her best friend, Oliver, Schuyler travels to Italy in the hope of finding the one man who can help--her grandfather. Meanwhile, back in New York, preparations are feverishly underway for the Four Hundred Ball, an exclusive gala hosted by the city's wealthy, powerful, and unhuman--a true Blue Blood affair.

But it's at the after-party, a masquerade ball thrown by the cunning Mimi Force, that the real danger lurks. Hidden behind the masks is a revelation that will forever change the course of a young vampire's destiny.

Rich with glamour, attitude, and vampire lore, this second installment in the Blue Bloods saga will leave readers thirsting for more.

This book is so much better than Blue Bloods. I have a feeling they are going to get better with each new one.
