Vicious interstellar conflict with an indestructible alien species. Bloody civil war over the last habitable zones of the cosmos. Political unrest, militaristic police forces, dire threats to the solar system...

Humanity is on the ropes, and after years of fighting a two-front war with losing odds, so is Commonwealth Defense Corps officer Andrew Grayson. He dreams of dropping out of the service one day, alongside his pilot girlfriend, but as warfare consumes entire planets and conditions on Earth deteriorate, he wonders if there will be anywhere left for them to go.

After surviving a...

The alien forces known as the Lankies are gathering on the solar system's edge, consolidating their conquest of Mars and setting their sights on Earth. The far-off colony of New Svalbard, cut off from the rest of the galaxy by the Lanky blockade, teeters on the verge of starvation and collapse. The forces of the two Earth alliances have won minor skirmishes but are in danger of losing the war. For battle-weary staff sergeant Andrew Grayson and the ragged forces of the North American Commonwealth, the fight for survival is entering a catastrophic new phase.

Forging an uneasy alliance...

The assault on Earth was thwarted by the destruction of the aliens' seed ship, but with Mars still under Lanky control, survivors work frantically to rebuild fighting capacity and shore up planetary defenses.

Knowing Earth's uneasy respite won't last, the North American Commonwealth and its Sino-Russian allies hurtle toward two dangerous options: hit the Lanky forces on Mars or go after deserters who stole a fleet of invaluable warships...

The time has come to take the fight to the Lankies.

Mars has been under Lanky control for more than a year. Since then, the depleted forces of Earth's alliances have rebuilt their fleets, staffing old warships with freshly trained troops. Torn between the need to beat the Lankies to the punch and taking enough time to put together an effective fighting force, command has decided to strike now.

Once again, seasoned veterans Andrew and Halley find themselves in charge of green troops and at the sharp tip of the spear as the combined military might of Earth goes up against the...

Humankind may have won the battle, but a new threat looms larger than ever before...

Earth's armed forces have stopped the Lanky advance and chased their ships out of the solar system, but for CDC officer Andrew Grayson, the war feels anything but won. On Mars, the grinding duty of flushing out the twenty-meter-tall alien invaders from their burrows underground is wearing down troops and equipment at an alarming rate. And for the remaining extrasolar colonies, the threat of a Lanky attack is ever present.

Earth's game changer? New advanced ships and weapons, designed to...
