The Hidden Concern, the criminal syndicate of uplifted octopodes who rule the oceans of Ceres, are hosting an exclusive auction with a million-credit buy-in, and many of the major factions in the Inner System are sending representatives. Up for bid is the ego of a corporate scientist, the genius who developed cortical stacks and made immortality available to the masses, a luminary who was thought to be lost during The Fall. Firewall has also purchased a seat at the auction, dispatching a team of Sentinels to prevent the ego from falling into the wrong hands. To do so, however, they’ll have to sneak past the octopus mafia’s paranoid security measures and outsmart some of the most well-equipped and ruthless transhumans in the system who also want the ego for themselves. Can they secure the ego and escape from the auction without touching off a bloody undersea war?
