“Shatnerverse” is an unofficial fan term for the continuity in which novels credited as written by William Shatner take place.

In this continuity, James T. Kirk was restored to life following his “death” in 2371, and went on to adventures involving former crewmates from the USS Enterprise (NCC-1701) as well as prominent 24th century figures.
