Shatner did it again! "Avenger" is a good book, but is isn't as good as "The Return". (But if you want to split hairs, I think you would be hard pressed to find a Star Trek novel better than "The Return") Although it features the Next Generation cast, this story is mainly about Kirk and Spock on their respective missions. Kirk to find the cure to the virus that has Starfleet placing entire star systems under quarantine. Spock searching for proof that his father Sarek was murdered. They intertwine with the Enterprise-E crew to make a story that will have you guessing until the end. It also does one heck of a job explaining Kirk's survival from the Borg Homeworld. "Avenger" also sets up the next novel in the series, "Spectre". A must read if you love Star Trek!
