Crossing the Bridge of Time

Thalia isn't the kind of girl with a best friend, or friends for that matter. But when a mysterious girl named Aiden with no background shows up at her school one Monday morning, Thalia can't help but get to know her. As the two girls become closer and closer, Thalia realizes that Aiden is hiding something, something big. Can Thalia figure out what Aiden is hiding, or will time slip by before she has the chance?
