Star Wars: Heir to the Empire: Behind the Scenes is a special recording that features new commentary by author Timothy Zahn and editor Betsy Mitchell, written for the 20th anniversary edition of Heir to the Empire, read by Zahn and Mitchell. Included here is audio from the that new unabridged recording to enhance their comments.

With the long-anticipated arrival of the founders in the Temples, Star Force's future will change drastically, one way or another. The time of anonymity is ended. Extra-galactic contact has finally arrived.

Ever since the Elders deemed him unworthy, Cal-com had been lost. He knew now, or at least suspected, what their true reasons had been, but it still didn't take the sting away in his exile. Cal-com's journey is not at an end. In fact, it's just the beginning....

The Paladin are able to bypass the Sphere's barrier shield by being grown inside from genetic material, expanding into an invasion army that leads to a confrontation with the Vargemma...and much, much more.

Death averted, mysteries revealed, and an entirely different challenge to face for the kings and queens of troubleshooting.

The Age of Superweapons has begun....

In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe.

Paul and Cal-com set off on their journey while the war against the Hadarak rages on.

A pivotal moment in Star Force history occurs, but far more than the public will ever know about.

As Paul's changes begin to unfold, secrets are revealed and Star Force's future takes a drastic turn.

With the Grand Border complete and holding and the deal with the Neofan long-since struck and mutually beneficial, a new shift is about to occur in the galactic powerbase.

In youth you'd lay awake at night and scheme.

Paul and Sara must find their way out of Gamma Temple, but they're not going to leave empty-handed.

Star Force is beyond frustrated by the continuing Vargemma attacks, but until a trailblazer or other Essence wielder can find a way to reach the Paladin, the portals will remained closed to the outside and the enemy will continue to be able to strike the empire with impunity.

This long-awaited culmination of the Agent of Change sequence of Sharon Lee and Steve Miller's internationally acclaimed Liaden Universe novels pits unexpected friends and unexpected enemies against each other in a war that spans planets and races - and threatens to bring interstellar violence to the very surface of fabled Liad.

Astrophysicist and best-selling author Mario Livio draws on his own scientific expertise to provide captivating insights into how Galileo reached his bold new conclusions about the cosmos and the laws of nature. A freethinker who followed the evidence wherever it led him, Galileo was one of the most significant figures behind the scientific revolution. He believed that every educated person should know science as well as literature, and insisted on reaching the widest audience possible, publishing his books in Italian rather than Latin.

The Complex Logic Laws were the result of a war waged hundreds of years in the past, when two human powers threw massive AI navies at each other and nearly annihilated themselves. Being human, they blamed their tools for this near miss; they destroyed what was left of the sentient ships, and made it illegal to be, manufacture, or shelter an independent logic.

There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "Big Bang", determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned", there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

Years ago, cosmologist Stephon Alexander received life-changing advice: to discover real physics, he needed to stop memorizing and start taking risks. In Fear of a Black Universe, Alexander shows that great physics requires us to think outside the mainstream - to improvise and rely on intuition. His approach leads him to three principles that shape all theories of the universe: the principle of invariance, the quantum principle, and the principle of emergence. Alexander uses them to explore some of physics' greatest mysteries.
