The Snow Queen (Vinge novel)

The Galactic Empire, which once ruled large portions of the galaxy, fell into decay millennia ago. Its remnants coalesced into a group of seven planets known as the Hegemony. Though the Hegemony has large-scale interstellar travel and high technology, it has not yet returned to the Empire's level of technological prowess.

Tiamat is an oceanic planet, accessible to the Hegemony only through wormhole travel. The gravitational pull of Tiamat's twin suns influence the "Black Gate". It only remains open for cycles of 150 years; when it is closed, no offworld travelers are able to reach Tiamat for more than a century. The residents of Tiamat are split into two clans: "Winters", who advocate technological progress and trade with offworlders, and "Summers", who depend on their folk traditions and rigid social distinctions for survival. Every 150 years, control of Tiamat's government switches between Winter rule and Summer rule. Interstellar travel between Tiamat and the Hegemony is only possible during the 150 years of Winter rule, and a single woman rules the entire planet: a "Snow Queen" in Winter, a "Summer Queen" in Summer. During the Change, or transition of power, the former queen is ritually executed and replaced by her successor in order to avoid open conflict.

The Hegemony's interest in Tiamat lies in mers, a species of sea-dwelling creatures whose blood contains a virus that halts the aging process. Mers are hunted as frequently as possible during the Winter years. The "water of life" produced from their blood allows for virtual immortality. A single Snow Queen reigns for the entire 150-year season. During Winter rule, offworlders bring technology to Tiamat in exchange for the water of life. At the end of Winter, they leave Tiamat and destroy all high technology, leaving Summers to rule under an agrarian lifestyle. In this way, they exploit Tiamat and prevent it from developing the technology to rebel.

Arienrhod, the Snow Queen, has secretly implanted several Summer women with clones of herself, in the hopes of extending her rule past her ritual execution at the end of Winter. Moon Dawntreader Summer is the only one of these clones to survive to adolescence. She and her cousin Sparks are lovers. Moon becomes a sibyl, a position of high status among the Summer people. Sibyls are both feared and revered; they possess the ability to answer any question by going into a trance state. Sibyls believe that they receive visions from the Lady, a sea goddess. Sparks is not chosen to become a sibyl. Angry at Moon for joining the sibyls without him and curious about his offworld heritage, he travels to Carbuncle, Tiamat's capital. He is immediately caught up by Arienrhod and eventually becomes the "Starbuck", the Snow Queen's consort and commander of the mer hunts.

Moon receives a message, apparently from Sparks, urging her to come to Carbuncle, though sibyls may not legally enter the city. On her way, she becomes entangled with smugglers and is taken offworld. This is normally a one way trip for a Tiamatan citizen. Hegemony law prevents any native Tiamatian from returning after leaving the planet, fearing that travelers would realize how Tiamat is being exploited and use this knowledge to foment rebellion. Arienrhod is crushed; she had planned to draw Moon to Carbuncle and make her the next Summer Queen. Moon was supposed to reject the Summer fear of technology and develop resistance to the Hegemony during the next Summer reign. Arienrhod devises a backup plan; she will unleash a plague at the Change which will kill most Summers and spare most Winters, allowing Tiamat to continue its technological growth before the Hegemony returns.

Moon is taken to the capital planet, Kharemough, and discovers that the Winters' prejudice against sibyls is a political tool used by the Hegemony to preserve its control of technology on Tiamat. Sibyls are highly respected throughout the other planets of the Hegemony; only on Tiamat, due to a careful reinforcement of superstitions during the reign of Winter, are they considered dangerous and mentally unstable. The sibyls are actually part of a data network devised by the Old Empire as a way to rebuild society more quickly after the Empire's fall. Sibyls have the ability to communicate with a vast electronic databank, which explains their ability to answer seemingly unknowable questions. Moon learns from another sibyl that Sparks is in danger, and returns to Tiamat illegally. Due to time dilation, five years pass on Tiamat while Moon is only gone for a period of weeks.

After a crash landing and short sojourn as a captive of Winter outlaws, Moon returns to Carbuncle and confronts Arienrhod. Arienrhod's plan to unleash the plague is foiled, but Moon is chosen to become the next Summer Queen. She prepares Tiamat to face the Hegemony as a peer when the 150 years of summer end and interstellar travel is again possible through the black hole.

Vinge wrote a sequel to The Snow Queen called The Summer Queen (1991), with a novella, World's End (1984), linking the two. A third novel, Tangled Up In Blue, was published in 2000.

Vinge’s novel was well received when it initially came out. Reviewers have admired the complex world-building Vinge created with the planet of Tiamat and the Hegemony calling it a “carefully crafted universe”[3] and “impeccable and expansive”.[4] Reaction to the characters and plot have been mixed. Some reviewers have seen the characters as “distinctive and believable”[4] while other reviewers have felt the characters too casual.[3] The plot has been called “fast-paced and eventful”[3] and “the kind of book that felt much shorter than the 500-odd pages in spans”[4] but also frustrating as “the love story holds very few surprises"[3] being based on the Hans Christian Andersen story. Some have said the book “feels before its time”.[4]
