Concluding William Shatner's first Star Trek trilogy is Avenger.
Following the adventures in Ashes of Eden and The Return as well as the movie Star Trek Generations, The Federation is being decimated by a mysterious virogen.
Captain Picard and the crew of the Enterprise E are tasked with keeping the infected at bay.
Meanwhile, Spock has learned that his father may have been partly responsible for the outbreak.
And Captain Kirk reappears to mess up both Picard's and Spock's plans.
With the two captains teaming up once again, which one will save the Federation? And is Spock destined to follow in his father's footsteps?
Avenger does not have the same fun storyline as the earlier novels. The plotline of an infectious disease doesn't carry much weight in a space opera.
This has been the weakest Shatner Star Trek novel so far.
