All right, I think this author took slightly more liberty with this novelization than “Gene Roddenberry” did with the first one; a lot of the scenes that I don’t remember from the movie are a little disparate (but nobody got implants that disappear). Given what I’ve seen of the novelization of The Search for Spock, though, this one is relatively bang-on the novelization.
To recap: While the Enterprise is on a training mission, it investigates a scientific lab outpost that sends a garbled message to Kirk. Meanwhile, an enemy from Kirk’s past has put events in motion to steal that lab’s discovery and to kill Kirk in revenge.
These books clock in under 200 pages, even with the additional emoting scenes and scientific mumbo-jumbo added. If you’re into Star Trek, you will probably get a kick out of them.
