Trek Lit Reviews has a review up for Gene Deweese‘s “Star Trek: The Next Generation: 2 The Peacekeepers“:
A planet on the brink of nuclear war suddenly discovers they are not alone in the universe when mysterious alien technology appears in orbit. One man takes control of the technology and uses it to halt the impending war by targeting the nuclear weapons on the surface and eliminating them. Can this imposed peace last? And just what is the purpose of the mysterious ship in orbit? The man in control of it hopes to find out when two visitors suddenly appear aboard the ship: Data and LaForge, who are believed to be the creators of the fantastic technology. They aren’t, of course, but they must find a way to get back to the Enterprise without destabilizing this world or violating the prime directive.
