Descendants of Rust

Bastion City is in chaos, and no one knows if the new arrivals are friend or foe. What will become of their escape plan, and will they get to Chace in time?
With the weight of expectation riding on Nyx's shoulders, the stakes have never been higher. She's got to save herself, her brother, and everyone else who's counting on her survival knowledge . . . if only she knew how to get them all out. It's back to the drawing board, but there's no way she's giving up her dream of freedom after coming so far, whatever the cost.
