War heroes aren't usually called out of semi-retirement and sent to the far reaches of the galaxy for a routine investigation. So when Colonel Carl Butler answers the call from an old and powerful friend, he knows it's something big - and he's not being told the whole story. A high councilor's son has gone MIA out of Cappa Base, the space station orbiting a battle-ravaged planet. The young lieutenant had been wounded and evacuated - but there's no record of him having ever arrived at hospital command.

From the Audie-nominated narrator of The Martian. In eleven years' time, a million members of an alien race will arrive at Earth. 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.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

They're sent to the past.

The Martian meets Gravity when Army Pilot Vaughn Singleton, Earth’s last man, rushes to Area 51 in search of a spaceplane after he discovers the last woman is stranded on the International Space Station and barely alive - thus beginning a race against time. The event that wiped life from the planet started at the supercollider. It created a rift in space-time. The astronaut stranded aboard the space station, Commander Angela Brown, is a theoretical physicist who used to work at the collider.

In the heart of the South Pacific lies Point Nemo, the most desolate and remote place on Earth. At its core is a dead zone, devoid of life, where government agencies crash their obsolete satellites and space stations, confident they won't harm a soul. When the International Space Station suffers a catastrophic failure and plummets through the atmosphere, it's here that Mission Specialist Julie Rohr, an astrobiologist studying living space dust called xylem, finds herself marooned. Julie's only hope for rescue lies in the hands of her estranged father, Dr. Finn Maddern, a renowned mycologist.

A human diplomat creates an interstellar incident when he kills an alien diplomat in a most unusual way. To avoid war, Earth's government must find an equally unusual object: A type of sheep ("The Android's Dream"), used in the alien race's coronation ceremony.

The fate of five worlds hangs on how their forerunners perform. Will Silas have what it takes to win Earth a place in the multiverse? Or will Earth become another mining world stripped of all resources and left a barren husk floating in the cosmos?
