Fear the Sky


Stephen Moss - 2014
    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. 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.

Columbus Day


Craig Alanson - 2016
    And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved. The UN Expeditionary Force hitched a ride on Kristang ships to fight the Ruhar, wherever our new allies thought we could be useful. So, I went from fighting with the US Army in Nigeria, to fighting in space. It was lies, all of it. We shouldn't even be fighting the Ruhar, they aren't our enemy, our allies are. I'd better start at the beginning....

The Myriad


R.M. Meluch - 2005
    M. Meluch's first novel in more than a decade, The Myriad, begins a series that is an amalgam of subgenres: military science fiction, space opera, time paradox, and alternate history.On an Earth where the Roman Empire never fell (but instead existed in secret societies for millennia, finally reestablishing itself on the planet Palatine) and is now embroiled in a war against the League of Earth Nations, a much more deadly foe emerges from the darkness of deep space -- the Hive. The governments of Palatine and Earth enter into an uneasy alliance to fight the alien invaders, nondescript antagonists that exist only to consume. While the unified forces try to keep the Hive from destroying human-populated planets, one U.S. battleship, the Merrimack, sets off on a quest to find the Hive's homeworld and take the battle to its source.During the ship's desperate search, the crew of the Merrimack discovers a strange star cluster with three worlds inhabited by sentient beings. After first contact with the amazingly humanoid populace, Captain John Farragut discovers a series of wormholes that could unlock the secrets that could defeat the Hive -- or destroy humankind forever.Vaguely reminiscent of Robert A. Heinlein's Starship Troopers (specifically, the relentless alien antagonists and the over-the-top, gung-ho characters), Meluch's The Myriad is lighthearted, fast-paced fun. While obviously not as intense or controversial as Heinlein's Hugo Award winning classic, this novel will prove thoroughly enjoyable to fans of military science fiction authors like David Weber and David Drake.
