Cypher

The invasion is over, but not all the aliens are gone. As the outside world learns what happened to the city, Violet and Bo struggle to keep their ally Gloom hidden from prying eyes. Those in power believe he is the key to unlocking the invaders' technology and will stop at nothing to capture him. All the while, the invasion's survivors are being drawn to a mysterious anomaly that might be their destruction—or their salvation from an even greater threat.
