The earth's fire

"All the years Ti'ana spend playing the ruthless game of survival had thaught her one thing. Always put your life and your safety above anyone else's. She knows she should have ran as fast as she could the moment she escaped. But for some reason unknown to her, she couldn't let the exasperating na'vi behind."

-When Ti'ana's sister, Varang, killed their father and took over the power over their clan, the young na'vi ran far away, to prevent having the same fate . But years later she is captured by the sky people that now work with her evil sister, and taken captive by them. She has to escape before Varang finishes what she couldn't in the past, and later find a way to end her sister once and for all.
Yet there was one complication. A certain earth na'vi was taken captive aswell. And for some reason, he had the very annoying effects of getting under her skin and make her care more than she should have.
