The Color of Rain

If there is one thing that seventeen-year-old Rain knows and knows well, it is survival. Caring for her little brother, Walker, who is "Touched, " and losing the rest of her family to the same disease, Rain has long had to fend for herself on the bleak, dangerous streets of Earth City. When she looks to the stars, Rain sees escape and the only possible cure for Walker. And when a darkly handsome and mysterious captain named Johnny offers her passage to the Edge, Rain immediately boards his spaceship.
Her only price: her "willingness." The Void cloaks many secrets, and Rain quickly discovers that Johnny's ship serves as host for an underground slave trade for the Touched .
