Finbar is a skinny, pale book lover who spends a great deal of time with his mother watching romantic movies and discussing books. He has a fraternal twin brother name Luke who is just the opposite - star athlete with girls flocking all over him. Even when people notice Finbar they think he is Luke's little brother.
The family has just moved from Indiana to New York. It is a chance to get away from the bully who has tormented Fin for years and start all over, but it makes little difference because he can't change who he is...or can he?
Fin overhears three girls talking about the latest vampire romance, Bloodthirsty, and how much they love the male vampire in the story. The more Fin thinks about it the more he realizes that he is a lot like a vampire - skinny, pale, brooding. And if this is what girls think is hot then he may have a chance to actually get a girlfriend. Fin decides he will become a vampire (not by getting bit or anything because the sight of blood makes him squeamish). You can't just go around announcing you are vampire, so Fin adopts the vampire attitude and drops subtle hints.
While he is working on his scheme, he meets a girl who actually seems to like him. Does she know he's a 'vampire'? Will she like him more if she does? The life of a pretend vampire can get complicated. When people start to believe it the rumor spreads and he is no longer just Luke's little brother.
