Infinite Days — Rebecca Maizel

She longs to be like everybody else. But her history is written in blood...

Lenah Beaudonte is in many ways your average sixteen-year-old: the new girl, she struggles to fit in enough to survive at school, and stand out enough to catch the eye of the golden-boy captain of the lacrosse team. But her challenges are beyond what anyone could have expected. Lenah just happens to be a recovering five-hundred-year-old vampire turned human...

She's just awakened from a century-long hibernation and each passing hour hears another tick of the time-bomb, counting down to the moment when her abandoned vampire coven will open the crypt where she should be sleeping, and find her gone. As her borrowed days slip by, Lenah resolves to live her newfound life as fully as the passing moments allow. But, to do so, she must first answer the ominous questions at hand: Can an ex-vampire survive in a time and place so alien to her? What can Lenah do to protect her new friends from the bloodthirsty menace about to descend upon them? And how is she ever going to pass her biology midterm?
