The Wayfarer, a patched-up ship that's seen better days, offers her everything she could possibly want: a small, quiet spot to call home for a while, adventure in far-off corners of the galaxy, and distance from her troubled past.

The client is paying a crazy sum - if the job is clean. That’s not going to happen. Instead, the galaxy’s unluckiest crew of outlaws will have to put all their resources into salvaging what they can from the job. Even if it’s only avoiding blame for the fallout.

Most days, Sarya doesn't feel like the most terrifying creature in the galaxy. Most days, she's got other things on her mind. Like hiding her identity among the hundreds of alien species roaming the corridors of Watertower Station. Or making sure her adoptive mother doesn't casually eviscerate one of their neighbors. Again. And most days, she can almost accept that she'll never know the truth - that she'll never know why humanity was deemed too dangerous to exist.

And they are wrong on every count. Only averagely tall, slender, and god-awful with a sword, Locke Lamora is the fabled Thorn, and the greatest weapons at his disposal are his wit and cunning.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire.

They're all gone. We remember them like yesterday: pieces of our stolen heritage. Things like NASA. Football. Parades and pies. Good things, comfortable things. We remember a time when we were alone in the universe, safe and oblivious. But it's all gone now. We called them the Telestines, and in the face of their ruthless invasion we were powerless. By 2040, all the world's governments and militaries had fallen, and the remnants of humanity exiled to the solar system. We looked down on our blue planet, so close to our birthplace, so close to our home.

Black Ops - the intelligence arm of the Meridian Alliance Fleet came calling with an offer Henricksen couldn't refuse: a ship - an entire squadron of ships, actually - and crew to command. A chance to get back to the stars. Too bad he didn't ask more questions before accepting the assignment. Too bad no one told him just how dangerous this particular skunkworks project was. They call the ship the RV-N: Reconnaissance Vessel-Non-combat, Raven for short. A stealth ship - fast, and maneuverable, and brutal as hell.
