Pushing Ice
Alastair Reynolds
 Pushing Ice begins in the distant future, where the elected rulers of the Congress of the Lindblad Ring gather to decide on a suitable ceremony to honour a woman they consider responsible for the technological advancement and territorial expansion of the future human race, Bella Lind. To explain her role, the chronology is then pushed back to the early days of humanity's manned exploration of the solar system, where it is explained that Lind is the captain of the Rockhopper, a spacecraft used for mining cometary ice. While on a routine mission, Lind is informed that Saturn's moon Janus has deviated from its normal orbit, and is accelerating out of the solar system. The Rockhopper, deemed the only ship capable of catching up to Janus, is asked to undertake the task of pursuing the moon, and sending back as much information as possible before being forced to turn back by the limitations of fuel and supplies. However, on their approach to the moon, revealed to be a camouflaged alien spacecraft, Lind and her crew are caught in the field of the ship's inertialess drive, causing them to travel further and faster than expected, and beyond their capacity to return to Earth. Realising their predicament, the crew decide to land on the moon and attempt to survive the flight out of the solar system, wherever it may take them. Eventually it becomes apparent that ship is heading towards Spica, a close binary pair in the constellation of Virgo. At one point before the landing, Bella's closest friend and subordinate, Svetlana Barseghian, pushes for Bella to turn the ship around while there is still a chance to return to Earth. Bella decides that turning back is too dangerous, angering Svetlana, who then leads a mutiny and, after the ship lands, exiles Bella to a structure set apart from the main colony. The novel traces the life of the colony for many years as they try to eke out an existence on Janus and determine why it is moving through space. They work out a way of deriving power from some alien technology they find, and slowly start to improve their living conditions. They eventually arrive at a vast megastructure where they meet an alien species, called 'Fountainheads'. The encounter with the benevolent aliens improves the colonists' situation dramatically. The alien presence is played poorly by Svetlana who loses control of the colony to Bella. Bella does not exile Svetlana, even if she chooses a form of self-exile. The Fountainheads are able to rejuvenate humans, healing injuries and making them younger. The only restriction is that they cannot heal brain damage without the patient losing part of his/her personality. Bella and several others undergo rejuvenation to make themselves younger. Those that are rejuvenated still age, but more slowly. Another several decades go by as the Fountainheads and the humans co-exist. The Fountainheads are trading advanced technology with the colony in exchange for drilling rights on Janus, whose core is a vast energy resource. The Fountainheads warn Bella of the arrival of another, repulsive (by human standards) race called Musk Dogs that will infect the colony and tear it apart in an effort to get at Janus' core. When they arrive, Svetlana meets with the Musk Dogs and trades with them, she tries to regain control of the colony, but her actions set off a chain of events that destroys Janus and requires everyone to evacuate. Svetlana, with the assistance of the Fountainheads, leaves the structure through the gap created by the explosion. Pictures from her ship reveal the structure to be a Torus the size of a planetary system, with part of the structure missing at its center (believed to be the Spicans' quarters). Bella dies during the evacuation of Janus, but her body is nonetheless brought along with the evacuating colony. Her body remains in stasis for decades, waiting for the Fountainheads to restore her to life; she eventually awakens to learn that a new human colony has been established elsewhere in the structure.
