Titan continue their line of novels based upon the original Star Trek series with #41 Mindshadow by J. M. Dillard. Due to publishing differences between the UK and the US this adventure actually precedes her other two novels so for the UK readers the correct sequence is #41 Mindshadow, #43 Demons and #6 Bloodthirst. This leads to some continuity for secondary Enterprise crew that Dillard has created who are rather important to the stories. The story centres around the planet Aritani. The Enterprise is asked to investigate as the planet is having trouble with pirates and privateers attacking their settlements. They are reticent about Federation help as they are not a member of the UFP and shun all technology as they believe to be destructive to a civilisation. Kirk is at a loss to understand why this backwater planet is of any interest and orders Spock to conduct and investigation. The investigation never takes place when Spock is found at the base of a cliff with a massive head trauma. Rather like #3 Dreams Of The Raven, we have to deal with a crewman who has lost part of his life to head injury but this time, in the case of Spock, his mind is the all important key to his continued survival. McCoy can only do so much and requests a medical specialist to rendezvous with them as fast as possible. Kirk meanwhile is busy with the pirates and the possible threat of Romulan intervention. Have they developed a new cloaking device? What is their interest in Aritani? Are the native population hiding something? While dealing with all of this, he also has to deal with the fact that there is a double agent on board. Unfortunately, this whole subplot is rather clumsy and obvious from the start and in the end could've been handled much better with a more subtle approach. There are several twists and turns in the story line but they all lead to rather simplistic conclusions. It's not a bad read but rather similar to the basic scripts that dominated season three of the show.
