Clouded Skies (Book 1 of the Fiyerra Series)

If you were different, not quite human... wouldn't you want a place to call home, a place where no one would ever find you? Welcome to Fiyerra, the only safe haven left for creatures straight from myths and fairy tales. But even here, war wages and blood is spilt. Can even the most powerful of creatures, known as Mythics, stop it?

Gwen is a nobody. A slightly klutzy, occasionally sweet, and sometimes sarcastic teenager. Even though she's quite an ordinary seventeen and a half year old with and ordinary life, somewhat extraordinary things begin happening. Suddenly everything she knows is turned upside down, and her life isn't so boring anymore! With her newfound companion Azrael, her long time almost-sister Cree, a few other... allies..., and a cast of occasionally-helpful-but-usually-annoying friends, she'll discover that a life full of Angels and Demons isn't always happily ever after...

Because this girl is key to something- something big. Something that will keep the peace between two groups of immortals who have been warring for generations. She could be the one to save the guardians of Heavan and Hell.

The trouble is, what exactly IS this girl?
