Motionpicturescomics.com has a review up for Greg Cox‘s “Star Trek: The Original Series: The Weight of Worlds“:
After reading Greg Cox’s novel The Rings of Time, I moved on to Mr. Cox’s next book: The Weight of Worlds. As was The Rings of Time, this book is set during the era of the Original Series and the Enterprise’s five-year mission. A Federation scientific institute at the edge of space is attacked by invaders from another dimension. These invaders use gravity-based weaponry to subdue the peaceful scientists and thinkers. When the Enterprise responds to the institute’s distress call, they are alarmed to discover that the aliens have converted every one of the institute’s inhabitants into true believers in the Truth that they espouse. Captain Kirk leads a rescue mission, but he and Spock are captured and sent to the aliens’ home dimension, while Sulu and security officer Fawzia Yaseen are trapped on the planet, surrounded by the fierce aliens and their captive converts. Meanwhile, when the aliens turn their gravity-based weaponry against the Enterprise, Scotty is grievously injured, leaving Uhura in command of the ship.
