AD 3580. The Intersolar Commonwealth has spread through the galaxy to over a thousand star systems. It is a culture of rich diversity with a place for everyone. A powerful navy protects it from any hostile species that may lurk among the stars. For Commonwealth citizens, even death has been overcome.

In 2204, humanity is expanding into the wider galaxy in leaps and bounds. Cutting-edge technology of linked jump gates has rendered most forms of transportation - including starships - virtually obsolete. Every place on Earth, every distant planet humankind has settled, is now a step away from any other. And all seems wonderful - until a crashed alien spaceship of unknown origin is found on a newly located world 89 light-years from Earth, carrying a cargo as strange as it is horrifying. To assess the potential of the threat a high-powered team is dispatched to investigate. But one of them may not be all they seem....

The year is 3326. Nigel Sheldon, one of the founders of the Commonwealth, receives a visit from the Raiel - self-appointed guardians of the Void, the enigmatic construct at the core of the galaxy that threatens the existence of all that lives. The Raiel convince Nigel to participate in a desperate scheme to infiltrate the Void. Once inside, Nigel discovers that humans are not the only life-forms to have been sucked into the Void. The humans trapped there are afflicted by an alien species of biological mimics.

Nine hundred thousand years ago, something annihilated the Amarantin civilization just as it was on the verge of discovering space flight. Now one scientist, Dan Sylveste, will stop at nothing to solve the Amarantin riddle before ancient history repeats itself. With no other resources at his disposal, Sylveste forges a dangerous alliance with the cyborg crew of the starship Nostalgia for Infinity. But as he closes in on the secret, a killer closes in on him because the Amarantin were destroyed for a reason.

In AD 2600, the human race is finally beginning to realize its full potential. Hundreds of colonized planets scattered across the galaxy host a multitude of prosperous and wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature's boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems, and throughout inhabited space the Confederation Navy keeps the peace.

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....

The White Tree (book one): In Mallon the dark magic of the nether has been banned for centuries. Its users have been driven out or killed. Its secrets lost. But the holy book of the nethermancers has just been found by a boy named Dante. As he works to unlock the book's power, he's attacked in the street. The nethermancers aren't gone—and they want their book back. Caught between death cultists and the law, Dante fights for his life, aided by his growing skills and a brash bodyguard named Blays.

They hunt us. They bomb our worlds for target practice. A star cluster in the constellation of Orion rotates once every 1,000 years. Those who rule there have an ancient tradition: When each cycle ends, they train their fleets by spilling the blood of lesser beings. The enemy fleets are coming again. In response, the Rebel Worlds gather their starships to face the terrifying threat, and this time humanity is asked to stand with them. The last time they considered Earth, Vikings in longboats were raiding English coastlines. Today, we're less primitive. Today, we're a target.

The galaxy remembers Hadrian Marlowe as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives - even the emperor himself - against Imperial orders. But Hadrian was not a hero. He was not a monster. He was not even a soldier. Fleeing his father and a future as a torturer, Hadrian finds himself stranded on a strange, backwater world.

Six million years ago, at the very dawn of the starfaring era, Abigail Gentian fractured herself into a thousand male and female clones: the shatterlings. Sent out into the galaxy, these shatterlings have stood aloof as they document the rise and fall of countless human empires. They meet every 200,000 years to exchange news and memories of their travels with their siblings.
