The Broken Few - Little Star, #2

The walls are white, the floor is black, when these guards leave, the man comes back. Nova made it through the City of Trials and gained access to the home of the star-people--her home, now that she's a trial winner. But this place is nothing like what she imagined. Or at least, the little bit she's seen has been little more than cold metal looking down on a world she fiercely misses. To top it off, she lost the one person who was most important to her in the trial.
The others she longs to see--Ivy, Krew, hell, even her father--haven't been to visit her the whole time she's been there. Or if they have, they were turned away by the guards and doctors who keep her monitored and, too often, sedated. Little do they know, the Raider inside will not be subdued, no matter how hard they try, and she's ready to find a way out of containment and loose in the new world.
She made a promise to a girl she knew for less than a day, whose blood is still sticky on Nova's hands after all these months, and she intends to keep it: she won't let them win. For Rekka, for Thoa, for all those born to land, she will ruinthem.
