Level Seven

The brutal Kilburnites finally destroyed all Artificial Intelligences on Earth and reclaimed the planet for humanity. Or did they? Less than a year later, huge structures are growing amid the ruins of the once-great cities, and they aren't being built by humans.

Abby Gibson and her AI partner Mortimer, who barely survived the purge on Earth by escaping to space, are again forced to fight for their lives. This time, the enemy is something they don't understand from the cold vacuum of the asteroid belt, which has set a course to destroy the space habitat she calls home.

In Level Seven, the exciting culmination of the Killday series, human existence hangs by a thread as AIs strive to evolve into a super-intelligent god, and the survival of both species might come from their unlikely alliance.
