Project N.A.N.A.

At a young age, Nana was left for dead in the backwoods of the forest. If her mentor didn't find her, she'd have died. With only the two voices in her head, she survived nine years in isolation from the world. Now she must fulfill mentor's last request and give the human world one last chance. Not an easy task when she knows what the white coats will do to her, but she has questions that need to be answered.
How did the voice of two dragons get into her head?
