How can I protect my brother when I'm falling for our alien captor?

One minute I was on a plane with my brother, and the next I - along with every passenger - was waking up on a prison planet overseen by vicious aliens and heartless robotic guards. I need to find my brother and get us out of here, but when I encounter Tetro I find myself wanting something else.

I can't trust the man in charge of overseeing all the terrible things happening to me, but there's more to the alien than his brusque exterior. And soon I realize that he wants out of this place just as much as I do. I shouldn't be falling for him, but how can I resist when his kisses break down my defenses?

We need to get out, but escape may not be so simple when we fall under the sadistic eye of the prison's owner. Is there a way to save my brother and keep Tetro close? Or will I be forced to choose between family and the alien I'm coming to love?
