In the first novel of the Kilo-Five Trilogy by Karen Traviss, set in the Halo universe, the collapse of the Covenant offers a glimmer of peace for humanity in 2553.

Meanwhile, Dr. Catherine Halsey, thought dead, navigates hidden dangers and ancient Forerunner technology in a slipspace bubble, revealing truths that could change humanity's fate and testing the loyalties of all involved.
