Shatnerverse Totality
The third series by William Shatner (with Judith and Garfield Reeves-Stevens). It was published over five years beginning in 2002.
During James T. Kirk’s heroic five-year mission as captain of the Starship Enterprise,™ a mysterious alien threat called “The Totality” commenced its stealthy invasion, intending to conquer the Milky Way galaxy as it had conquered the Andromeda. Now the time for secrecy has passed, and a war unlike any other has begun — one that threatens to destroy the Federation, first by bringing warp travel to an end, and then by absorbing all living matter into an unknown realm.
