Yet the currents of fate continue to pull Clank towards an uncertain destiny and away from his friends with greater force than even the storm that threatens to capsize the Sunken Hope. Haunted by an old friend and hunted by an old foe, Clank finds himself dragged down into the depths of a plot to resurrect the long-dead Devastation with a new and Wicked outcome that even the great Singularity could not predict.
