I liked this fourth volume, based on J.J. Abram's Star Trek, better than the previous one. The first story, Hendorff, is told through the perspective of a red-shirt and his interaction with the command crew, from Kirk to Uhura. The next tale gives the backstory to Scotty's assistant, the diminutive Keenser. On his home world he was tease by the other kids for being too big and they called him "monster" and taunted him. On the Enterprise, he's griping about how big everything is for him. Keenser's people had first contact with the Federation from George Kirk (Kirk's father) and it was at that point, when seeing the shuttle, that Keenser wanted to join Starfleet. Three years later he's the first cadet to graduate from his home world. Then he's assigned to various outposts, ships and finally Delta Vega, where we meet him and Scotty in the first movie.
Mirrored, the third and last story, deals with the "Mirror Universe". It begins with Scotty and Dr. McCoy talking about the possibility of alternate realities, then goes to one such reality in which the Terran Empire has just defeated the Klingons. Spock is in charge and this doesn't sit well with James Tiberius Kirk, who has a plan to get power. He goes to the prison planet, Rura Penthe, where the Romulan Nero has been imprisoned for the past twenty years. Kirk wants the information of how to control his massive mining ship. He gets the information and takes the ship to Vulcan, with the intention of obliterating that planet. Can Spock stop him or has he been destroyed along with the Enterprise? And which side is Uhura on? There's even an appearance by the older Spock, who has ended up in this reality rather than the one depicted in the first movie.
