De la Cruz has revamped traditional vampire lore in this story featuring a group of attractive, privileged Manhattan teens who attend a prestigious private school. Schuyler Van Alen, 15, the last of the line in a distinguished family, is being raised by her distant and forbidding grandmother. Schuyler, her friend Oliver, and their new friend Dylan are treated like outsiders by the clique of popular, athletic, and beautiful teens made up of Mimi Force, her twin brother, and her best friend. What they have in common is the fact that they are all Blue Bloods, or vampires. They don't realize that they aren't normal until they reach age 15. Then the symptoms manifest themselves and they begin to crave raw meat, have nightmares about events in history, and get prominent blue veins in their arms. Their immortality and way of life are threatened after Blue Blood teens start getting murdered by a splinter group called the Silver Bloods. This novel constantly name-drops and is full of product placements, drinking, drugs, nonexplicit sex, and superficial characterizations, but the intriguing plot will keep teens reading. De la Cruz's explanation for the disappearance of the Colony of Roanoke is unique and the idea that models don't gain weight because they are Blue Bloods rather than anorexic is unusual.

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.

Have you ever wondered what secrets lurk behind the closed doors of New York City's wealthiest families? They're powerful, they're famous... they're undead.

Schuyler Van Alen's blood legacy has just been called into question--is the young vampire in fact a Blue Blood, or is it the sinister Silver Blood that runs through her veins? As controversy swirls, Schuyler is left stranded in the Force household, trapped under the same roof as her cunning nemesis, Mimi Force, and her forbidden crush, Jack Force.

When one of the Gates of Hell is breached by Silver Bloods in Rio de Janeiro, however, the Blue Bloods will need Schuyler on their side. The stakes are high; the battle is bloody; and through it all, Carnavale rages on. And in the end, one vampire's secret identity will be exposed in a revelation that shocks everyone.
