Hidden - Marianne Curley

Ebony has always known that she is different. Her violet eyes mark her out, and her protective parents have kept her in a gorgeous valley, home-schooled, safe from everything - almost as if she's being hidden. But she's changing: glowing, getting more and more beautiful, and stronger than anyone knows. Ebony can't stay hidden for ever, and when she meets complicated, intense Jordan, something explodes inside her - something that can be seen from the heavens; something that changes everything. Ebony is a stolen angel, concealed on Earth. Now the heavens have found her, they want her back.
