Eight Grade Bites (The Chronicles of Vladimir Tod) by Heather Brewer

Vladimir Tod, 8th grader, "goth boy" and punching bag for the 8th grade bullies also happens to be a half vampire who just lost his parents (vampire father, mortal mom) in a mysterious freak fire, and the best friend of Henry, who Vlad accidentally bit when they were 8 years old.

As if 8th grade weren't hard enough, he's also being followed by a mysterious substitute teacher who seems to know his secret.

This is an action-packed read, even for reluctant readers and Vlad is likeable as the dorky vampire whose caretaker, Nelly, keeps him supplied with his blood from the local blood bank. No human feasting in this one.
