The String Theory trilogy takes place during Voyager’s years in the Delta Quadrant and is structured as a three-part story rather than a set of standalone books. Cohesion, Fusion, and Evolution were published in 2005 and 2006 and involve the crew encountering a phenomenon that draws on ideas from string theory and theoretical cosmology.

The trilogy was a collaborative project among multiple authors, with the three volumes designed to be read in sequence. It represents one of the more ambitious storytelling attempts in the Voyager novel library up to that point, using a connected arc rather than episodic plotting.

For readers working through the Voyager novel back catalogue, String Theory sits in the middle period between the early standalone tie-ins and Kirsten Beyer’s post-series continuation novels. It is worth reading as a standalone story set during the Delta Quadrant years, particularly for readers who enjoy the science fiction concepts the show occasionally explored in its more ambitious episodes.
