book four:

Rise of avalon

Arthur's imprisoned and unsanctioned augmented humans are on the verge of being outlawed and contained.

It's been years since the capture of Arthur. Avallach and the Chevalier Corps have merged to become the Kin, a dominant augmented human force around the world. But the world is changing. The Augmented Human Weapons Convention has passed, which outlaws anyone who does not have a registered augmented human force--that is, anyone but the five UNSC powers.

Leto, frustrated at the lack of progress in Arthur's trial, formulates a new plan. He knows of the Prophecy--and is taking steps to prevent it from happening. He creates an alliance between the American Centurions and the Russian Cosmos augments and hatches a plan to stop the Kin for good.

Gal Brand is the Prophet. There's only one problem--she's lost her ability to see the future. Armed with only her mother's memories and her father's new power suit, she takes a team on a quest--a quest for the Grail to save her father and lead humanity through its next phase of evolution.

Will she succeed or drive humanity backward into another Dark Age?
