Doppelganger (excerpt)

Citrus Leahy is having a really bad day. First she's late to school. Then she runs into the girl who drives her nuts because she always calls her Orange instead of her name. To cap it all off, though, when Citrus finally makes it to class, she sees herself already inside. Wait. What? Citrus Leahy has a doppelganger, it's probably aliens taking over the world, and her life has just turned totally upside down. Goodbye, normal. Hello, paranormal. Luckily, her crush Aedan has the exact same problem!
