> Disc picks up right after Vaz and Tiona's invention of an apparently reactionless drive in Tiona. Tiona and her brother, Dante, want to license the rights to the new thrusters to big aircraft and car companies, using the money from the licenses to develop a private space industry. Vaz, their scientifically brilliant but socially inept father, has little interest in such a project but is happy to have them run with it. So they set out to convince doubtful major corporations that thrusters will change the world as we know it.

When the Colony on Hayden's world went black, a team was sent to investigate.

Circumstances have prevented outright warfare - until now.

What if it were possible to upload years of knowledge into your mind in hours? To become an expert in multiple scientific fields, become an MD, or learn several languages - in a single day?

But when she crosses paths with Kevin Quinn, a Secret Service agent desperately trying to kill the president, she finds herself at the epicenter of an insidious plot.

Could Elma really leave behind her husband and the chance to start a family to spend several years traveling to Mars?

Aliens exist...and, as it turns out, most of them are fairly harmless. It's the humans you need to watch out for. Priya Radcliffe wasn't even born yet when the first set of terrorists struck. She was 17 when they struck again, but this time her parents paid the ultimate price.

Dib is an Earthlike planet, only slightly smaller, with shorter days and longer years, in orbit around twin suns. On the continent of Geo, in the city of Velon in the nation of Inimata, a man lies dead in his study. In life, Professor Orno Linus was a world-class scholar: an astrophysicist, a dead-language linguist, and an expert in (and apparent true believer of) the religious concept of the Cull, i.e., the end of the world. Widely respected, nothing about Linus’s expertise suggests somebody might want him dead.

When Asha said she wanted to give the Chinese hackers a piece of her mind, she didn’t mean it literally. But that’s what happens when medical technology goes awry. Doctors said they could train her brain to interpret digital signals from the camera in her artificial eye. The module even has Wi-Fi so they can monitor signal traffic across her optic nerve. What they didn’t anticipate was that her brain would figure out how to use the Wi-Fi connection both ways. Asha can now see the internet.

In a grim future, astronomers discover the solar system’s long-theorized ninth planet, triggering an unprecedented space race, but not between countries. Instead, two mega corporations battle fiercely for primacy. Each wants to be the first to launch their probes into the darkness beyond Neptune.
