His past. Her future. Can love bring them together in time?

Abby's senior year of high school is textbook perfect, until she meets Dante Alexander, a foreign-exchange student from Italy. Time behaves differently when they are together - too fast, too slow, or seeming to stop entirely.

When the band Zero Hour performs at the local hangout, they exert a bizarre influence over their audience, ensnaring Abby's best friend, Valerie.

Dante helped Leonardo Da Vinci build a time machine, only to be falsely accused of being a traitor and sent over 500 years into the future as punishment.

As past and present collide, Abby learns she holds a special power over time itself.
