Hidden Power by Fiona Starr

A shifter, three sexy mages, and an Elemental with magic thought to be extinct… what could possibly go wrong?
I was born the day my parents died—talk about luck. I grew up bouncing around the foster system, never knowing when the rug would be pulled out from under me. Now, I’m twenty-two and while I’m free of the dangers of my childhood, life still isn’t easy.
When a strange couple appears chanting in some weird language, I try to walk away, but the guy whips out a freaking fire lasso and starts making like he’s going to hogtie me right there on the street. That’s when all kinds of crazy breaks loose. Next thing I know, I’m strapped to a bed in what looks like a hospital, I can’t speak, and some woman is telling me I’m a Vox Elemental, which leaves me a choice between getting shipped off to a magic school to train my voice or be silenced forever.
Of course I choose the school; who wouldn’t? Turns out my new home is a highly competitive, cut-throat academy where one wrong step could cost me everything. I promise myself that I’ll work hard and get free, which all goes out the window when I meet not one, not two, but four of the hottest guys I have ever seen, and they are definitely not part of the curriculum. As if juggling new relationships, a new school, and some rather testy mean girls weren’t enough, there’s also someone or something making a meal out of the student body—literally. Add that to the things I have to manage. Assuming I survive…
Some luck, huh?
