The Spellspinners Series by Diane Farr

Zara Norland has a problem. It's getting harder to hide who-or what-she is. Which is pretty ironic, actually. Because Zara doesn't know who, or what, she is. Enter Lance: Incredibly hot, supernaturally powerful, and full of answers to questions she hasn't even thought to ask. But is everything he says true? Now Zara must decide if Lance is the love of her life or her enemy. Which world does she belong to? And is the choice really hers?

All Zara wants is to finish high school like any ordinary girl. Problem is, Zara is no ordinary girl. And when Lance Donovan shows up in her homeroom, she fears her days at Cherry Glen High are numbered -- because Lance is a creature of power, with other plans for her life. Can Zara resist his pull? And, more importantly -- should she? Dark forces are converging on Cherry Glen, and Zara's decision could change her life forever ... or end it.
