Starship Eternal


M.R. Forbes - 2015
    A dire warning from futures past... A desperate search for salvation… Captain Mitchell “Ares” Williams is a Space Marine and the hero of the Battle for Liberty, whose Shot Heard ‘Round the Universe saved the planet from a nearly unstoppable war machine. He’s handsome, charismatic, and the perfect poster boy to help the military drive enlistment. Pulled from the war and thrown into the spotlight, he’s as efficient at charming the media as he was at shooting down enemy starfighters. After an assassination attempt leaves Mitchell critically wounded, he begins to suffer from strange hallucinations that carry a chilling and oddly familiar warning: They are coming. Find the Goliath or humankind will be destroyed. Convinced that the visions are a side-effect of his injuries, he tries to ignore them, only to learn that he may not be as crazy as he thinks. The enemy is real and closer than he imagined, and they’ll do whatever it takes to prevent him from rediscovering the centuries lost starship. Narrowly escaping capture, out of time and out of air, Mitchell lands at the mercy of the Riggers - a ragtag crew of former commandos who patrol the lawless outer reaches of the galaxy. Guided by a captain with a reputation for cold-blooded murder, they’re dangerous, immoral, and possibly insane. They may also be humanity’s last hope for survival in a war that has raged beyond eternity.

Old Man's War


John Scalzi - 2005

The bad news is that planets fit to live on are scarce-- and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding.Earth itself is a backwater. The bulk of humanity's resources are in the hands of the Colonial Defense Force. Everybody knows that when you reach retirement age, you can join the CDF. They don't want young people; they want people who carry the knowledge and skills of decades of living. You'll be taken off Earth and never allowed to return. You'll serve two years at the front. And if you survive, you'll be given a generous homestead stake of your own, on one of our hard-won colony planets.John Perry is taking that deal. He has only the vaguest idea what to expect. Because the actual fight, light-years from home, is far, far harder than he can imagine--and what he will become is far stranger.

Their technology is vastly superior to ours, and they know they cannot possibly lose the coming conflict. But they, like us, have found no answer to the destructive force of the atom, and they have no intention of facing the onslaught of our primitive nuclear arsenal, or the devastation it would wreak on the planet they crave. So they have flung out an advanced party in front of them, hidden within one of the countless asteroids randomly roaming the void. They do not want us, they want our planet. Their Agents are arriving.

Her chosen world is Callay, and its enormous, decadent capital metropolis of Tanusha, where the concerns of the war are literally and figuratively so many light years away. But the war between the League and the Federation was ideological as much as political, with much of that ideological dispute regarding the very existence of artificial sentience and the rules that govern its creation. Cassandra discovers that even in Tanusha, the powerful entities of this bloody conflict have wound their tentacles. Many in the League and the Federation have cause to want her dead, and Cassandra’s history, inevitably, catches up with her. Cassandra finds herself at the mercy of a society whose values preclude her own right even to exist. But her presence in Tanusha reveals other fault lines, and when Federal agents attempt to assassinate the Callayan president, she finds herself thrust into the service of her former enemies, using her lethal skills to attempt to protect her former enemies from forces beyond their ability to control.
