Perfect Ruin (The Internment Chronicles #1)

On the floating city of Internment, you can be anything you dream, unless you approach the edge. Morgan Stockhour knows getting too close can lead to madness, like her older brother Len, a Jumper. She takes solace in her best friend Pen, and in Basil, the boy she’s engaged to marry. When she investigates the first murder in a generation, she meets Judas. The suspect was betrothed to the victim, but Morgan believes he is innocent. Nothing can prepare Morgan for the secrets she will find – or whom she will lose.
