This is the way the world ends...for the last time. It starts with the great red rift across the heart of the world's sole continent, spewing ash that blots out the sun. It starts with death, with a murdered son and a missing daughter. It starts with betrayal, and long dormant wounds rising up to fester.

Years before they enter orbit, their approach will be announced by the flare of a thousand flames in the sky, their ships' huge engines burning hard to slow them from the vast speeds needed to cross interstellar space. These foreboding lights will shine in our night sky like new stars, getting ever brighter until they outshine even the sun, casting ominous shadows and banishing the night until they suddenly blink out.

The rich, the powerful, they lived their lives at the rate of one year every 10. Some created two societies: that of people who lived out their normal span and died, and those who slept away the decades, skipping over the intervening years and events. It allowed great plans to be put into motion. It allowed interstellar empires to be built.

Until, that is the discussion of his star student Elzbietá Abramowski's dissertation on Operation Oz, the Pacific Allies' invasion of Vladivostok, was brutally interrupted. The psychotic episode that turned his entire world upside down struck with absolutely no warning, and it was more terrifying than anything he should have been able to imagine.

Jain was the lieutenant commander of an elite SEAL team.

His mind had become its AI core. He is somewhere in deep space. Most of his systems are badly damaged. He has no memory of how he got here, or what his mission is.

Boss loves to dive historical ships, derelict spacecraft found adrift in the blackness between the stars. Sometimes she salvages for money, but mostly she's an active historian. She wants to know about the past--to experience it firsthand. Once she's dived the ship, she'll either leave it for others to find or file a claim so that she can bring tourists to dive it as well. It's a good life for a tough loner, with more interest in artifacts than people.

In the year 2031, a robot probe detects traces of biological activity on Enceladus, one of Saturn's moons. This sensational discovery shows that there is indeed evidence of extraterrestrial life. Fifteen years later, a hurriedly built spacecraft sets out on the long journey to the ringed planet and its moon. The international crew is not just facing a difficult twenty-seven months: if the spacecraft manages to make it to Enceladus without incident it must use a drillship to penetrate the kilometer-thick sheet of ice that entombs the moon.
