.. the film, called just Star Trek, and this novel, focused on very similar themes and events. Both feature a young Kirk on a troubled path, described as a “delinquent,” and showing his journey of redemption and acceptance into Starfleet. The film, while decried by some as not in keeping with the Star Trek of the past, proved to be a commercial and critical success, launching a new film series that renewed interest in the somewhat flagging franchise. Given the similarities between the film and the novel, but also the inherent differences due to each taking place in a separate timeline from the other, it is understandable that the proposed novel trilogy was cut short after just the first novel.
However, it is unfortunate, because Collision Course is actually pretty good.
