Why is my life so last century?
My name is Lily, I'm 13, and I have a big secret: every New Year's Eve when the clock strikes midnight, I time travel to a totally different era. Talk about inconvenient.

Luckily my cat, my best friend, and my not-so-secret crush always turn up, too. But why is my archnemesis, Georgia, so good at ye olde insults? How does anyone survive in ancient times without chicken nuggets? And why on earth can't I stay in one century?!
