How art thee similar to Star Trek? Let me count the ways. Thou art the Federation's Commonwealth's pride of fleet, on missions of first contact goodwill. Thou has an alpha bridge crew whom is active for every major encounter. An interspecies crew thee maintain, providing regular cultural confrontations. Boldly thee go, where no one has gone before.
Take an entire season of Star Trek, extract all the exciting discoveries and crises, inject them into a 289 page book, and you have Starplex. I exaggerate, of course, but only slightly. This did indeed have a succession of wondrous and dramatic developments - far more than should have been possible in novel of this length. This made for a fun and easy read but was far less satisfying than it could have been.
I, in fact, enjoy Star Trek, thus the comparison is not entirely unfavorable. Starplex, however, read as if it were written for television audiences, and it incorporated all the regrettable devices associated with that medium: a small company of characters take on multiple and overly broad roles (to simplify the story and cast), ordinary events are ratcheted up to the level of drama (so viewers readers stay tuned) personnel are faced with "crisis" decisions which they appear entirely unprepared for, despite the fact that they would have been repeatedly faced with the problem before (even more drama!), inappropriately-placed and melodramatic interpersonal scenes (keeping in touch with our sensitive side), and a completely unjustifiable disordered timeline (to be edgy). One might be able to condone these elements in a television series because of the format and audience, but I expect more consideration and a higher regard for readers.
Starplex, despite the obvious similarities to Star Trek, does provide something above and beyond the television series. Its hard science fiction attributes at first, read as info-dumps. I began to appreciate them more as the book went on. Though they were often ill-placed and broke momentum, Sawyer was more than adept at succinctly conveying complicated processes. Best of all, however, was that the book was actually about something - about real astrophysics questions. This will not be regarded as the scientific answer to those technical questions, but it was a fun story built around legitimate physics phenomena. That, along with the thriller and discovery attributes, made for a memorable story and enjoyable read.
