Captain Herix Trellis just wanted to command the UPS Alpaca, not fight to the death against a vicious reptilian alien species known as the Gorkeens. One year after crash-landing on an unknown planet and with his crew dispersed, there isn’t much hope of a rescue. One issue is they got there by a portal they couldn’t avoid, and now they have no idea where they are or when. Another problem is that over half the crew has been enslaved and used for food. It also doesn’t help that another third of the crew escaped and has not been heard from since.

The location: London. The date: Very, very soon. Beset by multiple crises and buried under a growing mountain of debt, the leaders of the G7 have taken the only logical decision. They've sold the planet. When Toby, a penniless student, and his two new flatmates find out one morning on TV, they're surprised to find the Earth's new alien owners are staggeringly cute and bring the promise of a debt-free future. They're just getting ready to celebrate along with the rest of the world, when a chance encounter with a mysterious professor reveals the truth.

There is a starship in trouble, lost in the void, with no one awake to hear the alarms. A thousand specially selected people left a troubled and unsustainable Earth for another world. Their dream was a new start on a virgin planet 30 years away. Their ship was state-of-the-art and entirely automatic, it's passengers safely sleeping through the journey - but something has gone wrong, something unexpected.

Technology has developed to the point where a person can be placed in a sleep state: a cross between suspended animation and a drug-induced coma. Just as the trial of the new technology is being completed, an unusual comet is discovered approaching Earth, bringing with it radiation that will wipe out all life on the planet.

After more than 20 years in special operations, USMC Gunnery Sergeant Wolf Mathison wasn’t looking forward to retirement when—implanted with an experimental artificial intelligence—he deployed on his last mission with a platoon of Marine Raiders being sent to the Jovian moon Europa. The USS Jefferson was destroyed en route, though, and only Mathison and three other marines survived. Trapped in stasis, they were hurled into the outer reaches of the solar system, where they wouldn’t be found for hundreds of years.
