Shadow's Edge — Maureen Lipinski

My magical life is dead to me now . . . This is my last chance at freedom.

Once, Leah Spencer didn't mind being a natural-born Shaman to the Créatúir, a human helper to faeries, shapeshifters, and other magical beings. But that was before she listened to her friend Fiona and broke Rule #1, traveling unprepared to the Other Realm where she quickly lost a whole year of time. She missed out on everything -- holidays, school, her sixteenth birthday, the boyfriend who ditched her. After that, Leah swore to leave all things magical behind and lead the life of a normal high school girl.

Now Fiona is missing, and something is killing off the Créatúir, both Light and Dark. As the Créatúir prepare to go to war, Leah is torn between her safe new life and solving the Other Realm murder spree. With the help of her three sisters (each with her own magical gift), and three gorgeous guys -- who may or may not be part of the evil magic -- Leah must vanquish an ancient dark force. Unless an unimaginable secret about her family destroys her first.
