The Enemy Stars was originally a story copyright 1958, then partially rewritten and republished in 1979. This edition is copyright 1987 and includes a sequel titled “The Ways of Love.”
In this far future setting, humanity has reached the stars, with ships that take potentially centuries to reach their destination, but the ships themselves can be reached instantly by matter-energy transporters not unlike Star Trek transporters only with an unimaginably vast range. The range of the machinery if it is powerful enough is practically infinite, but it must have another matter-energy transporter to lock on to. Space explorers can go back and forth to starships, meaning they don’t have to be crewed at all times, and the starships are sent out to help establish end points at systems that are worth colonizing, that once the starship makes the long, slow voyage to a system, humans can pour through the portal in seconds and start colonizing that world.
Earth has a tight grip on the colonies, with a dictator known as the Protector (the state known a the Protectorate) maintain dominance over the far-flung colonies, making it easy to journey to the colonies, but incredibly difficult to return to Earth, pretty much impossible for anyone born in the colonies. The colonies chafe under the Protectorate, but so far lack the power and organization to throw off that yoke (not that people on Earth have it great either, as a rigid caste system as well as a patriarchal rather misogynistic society exists).
The book details a mission to explore a dead star, one that is a featureless black sphere, darker than the endless night sky it exists in, made possible to explore by a slight diversion of the farthest out of the starships, the _Southern Cross_, sometimes called simply the _Cross_. Four men are sent out by matter transporter to the ship to explore this star, but in the course of the mission the four people become stranded in the system, fighting a series of challenges to not crash into the star, find a way to return home, to not starve, and to not go mad. The remainder of the book is how these four survive (or do they?), their philosophizing as to what is really important in life and why humanity is among the stars (this philosophizing echoed by the father and wife of one of the four men on board the ship, who back on Earth comes to terms with what has potentially happened to their loved one, David Ryerson), and as one might guess from the cover art, the mission leads inadvertently to first contact with a sentient alien species (the exact scene on the cover is in the book), with this having huge ramifications for all the characters and the setting as a whole.
I liked the different chapters early on as we are introduced to the different main characters, vivid little vignettes of each person’s life and their world before boarding the _Southern Cross_. The “man against nature” survival of the _Cross_ was interesting, and I loved the vivid description of how remote and cold and uncaring and isolated that super distant system was, with passages like “but the mind sensed remoteness beyond remoteness, and whimpered. Nor was the ground underfoot a comfort, for it was almost as dark,” though in the end, for as uncaring as the dark of deep space was, love of a husband and wife, love among friends and comrades, love for exploration and duty and yes even space, love for freedom, and love among totally different peoples, prevails.
