A Sky So Hollow

Some wounds never heal. . .

It's been a few months since Casper Bell saved Novilem from crumbling under the pressure of revolution. The dust hasn't settled, and neither has his nerves. A strange sickness is spreading in the city, and Casper is having visions about the tower Jacob sent to the Surface. Helix convinces him to bring his concerns to the Estellar council, but Helix's trust in the system backfires. They send the pair to the last place Casper wants to be: Earth.

Casper's past is right where he left it and corrupted aether still creeps on the streets of Chicago. When they find someone who is aether sick, it is clear they haven't finished uncovering the council's secrets.

With their friends and family falling sick, the fragile peace in Novilem collapsing, and the council ready to abandon the home they have fought so hard to protect, Casper and Helix must confront their inner darkness before Novilem is lost forever.

The sequel and series finisher to A Circle of Stars.
