«Chameleon» by Maggie Faire

Camryn Painter is a 16-year-old freak of nature. Or possibly the savior of a civilization that isn’t supposed to exist. She’s a human chameleon… one who transforms into the image of whoever she sees.

Escaping from a medical research facility, Camryn discovers a magical forest world. Not that she’s welcome. Her new home is filled with faeries and beasts set on destroying her. Striking a tribal alliance between what she once believed were mythical beings is her only chance of survival… if she can just control her power and figure out who to trust.
