More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

Bob Johansson didn't believe in an afterlife, so waking up after being killed in a car accident was a shock. To add to the surprise, he is now a sentient computer and the controlling intelligence for a Von Neumann probe. Bob and his copies have been spreading out from Earth for 40 years now, looking for habitable planets. But that's the only part of the plan that's still in one piece.

Thorn is back. He's lost one civilization, and is still trying to fix two others. But fixing something when you don't know how it broke is never as simple as you'd think. The future is threatened by his own past, and to fix everything, he thinks he has to undo what he's already done. But what if what you did cannot be undone, and the future has more riding on it than anyone knows? Yesterday's Spacemage was the cause. Today's Spacemage was the effect. But can tomorrow's Spacemage save everyone?

The Dread Empire of the Shaa is no more, following the death of the last oppressor. But freedom remains elusive for the myriad sentient races enslaved for 10 centuries, as an even greater terror arises. The Naxids - a powerful insectoid species themselves subjugated until the recent Shaa demise - plan to fill the vacuum with their own bloody domination and have already won a shattering victory with superior force and unimaginable cruelty. But two heroes survived the carnage at Magaria: Lord Gareth Martinez and the fiery, mysterious gun pilot Lady Caroline Sula.

The surviving Méridiens have returned to Confederation space, aided by their recently discovered cousins, the New Terrans. They expect a celebration after their 71-year absence. Instead, they're shocked to find the silver ships have destroyed half the Confederation. The Méridiens are fleeing in advance of the horde of alien ships. But Alex Racine and his crew didn't come this far to run away from humanity's enemy.

Mal wins an old map in a card game. Ancient and written in impenetrable symbols, the former owner insists it's worthless. Yet River Tam can read it, and says it leads to one of the Arks - legendary ships that brought humans from Earth-that-was to the 'Verse. The salvage potential alone is staggering. But the closer they get to the ancient ship, the more agitated River becomes.

Set against the backdrop of China’s Cultural Revolution, a secret military project sends signals into space to establish contact with aliens. An alien civilization on the brink of destruction captures the signal and plans to invade Earth. Meanwhile, on Earth, different camps start forming, planning to either welcome the superior beings and help them take over a world seen as corrupt, or to fight against the invasion.

In the distant future, humans and several other races have been granted membership in the Confederation - at a price. They must act as soldier/protectors of the far more civilized races who have long since turned away from war.

Hugo Award winner Harry Turtledove is the master of alternate history. In American Front he envisions World War I as it may have been if fought on American soil. The United States and Germany clash with the Confederacy, France, and Britain as the machines of modern warfare litter the landscape with carnage. Meanwhile, oppressed southern blacks head toward a fateful confrontation.

After being court-martialed by the Space Legion for ordering the strafing of a treaty-signing ceremony, multimillionaire Willard Phule receives his punishment: He must command the misfit Omega Company on Haskin's Planet, a mining settlement on the edge of settled space. At his duty station, he leverages his personal money and a knack for managing people to get the company to come together as a unit.

Gunnery Sergeant Torin Kerr was a Confederation Marine's marine. She'd survived more deadly encounters---and kept more of her officers and enlistees alive---than anyone in the Corps, and she was determined to keep that record intact. But since her last mission, she'd been sidelined into endless briefings and debriefings with no end in sight. So, of course, she'd jumped at the chance to go to Crucible---the Marine Corps training planet---as a temporary aide to Major Svensson.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

It was the perfect solution - put highly connected Captain Willard Phule in charge of the worst dregs of the Space Force. Sure, Phule's Company may be a band of rejects and misfits, but they did manage to save the day with their unorthodox methods. Embarrassed, the Space Force may have found the perfect equation for disaster: Assign Phule's pack of oddballs to save the Fat Chance Casino from a criminal take over. Phule's Company may stop the mob...but who will save the casino from them?

Miles Vorkosigan graduates from the Barrayaran Military Academy with high expectations of ship command, but is disappointed with an assignment as meteorologist to Lazkowski Base, an arctic training camp. His tenure in the windy, snow-covered north is cut short when Miles narrowly averts a massacre between the trigger-happy base commander and mutinous recruits. After a brief stay under 'house arrest', Miles is re-assigned to investigate a suspicious military build-up near a wormhole nexus.

Paradise falls. Humanity is thrown back to an age of steel and blood. Now the fuel that powers the "changed" world is up for grabs in an orbiting spacecraft. With only days to plan, rough and ready paladin Herzer Herrick must assemble a team of expert warriors capable of both seat-of-the-pants engineering and hand-to-hand combat in space. In the meantime, Herzer must face his own demons. And if that's not enough, there's a horde of "changed" orcs and goblins who are intent on delivering the power above to their totalitarian masters below.

Collected in one volume is all three books in C. J. Cherryh's epic The Faded Sun trilogy: Kesrith, Shon'jir, and Kutath.

Neapolis: a desert city on planet Bethel where all manner of entertainment is found: High-stakes gambling, luxurious hotels, exclusive clubs, and any form of diversion imaginable may be had for a price. It’s the eve of the annual carnival: three days of decadent revelry, and Serenity arrives to take a security job, guarding a costly shipment. But the shipment is stolen, and the wealthy owner kidnaps Zoë and Book, holding them to ransom for the lost shipment’s value. If Mal can’t find the enormous sum of 500 platinum by the next evening, both of them will be killed.

Although the exciting military career she hoped for never got off the ground, Ky Vatta ended up seeing plenty of combat when she took the helm of one of the commercial transport vessels in her family's fleet...and steered it into a full-blown war. Now the lessons she learned in that trial by fire are about to pay off---because this time, the war has come to her. Someone has launched a full-throttle offensive against Vatta Transport Ltd., Ky's father's interstellar shipping empire.

When asubatomic physics experiment causes a massive explosion, interdimensional gateways open in Florida - and aliens pour out. Some intend to bring Earth to its knees. Others seem willing to help, but will annihilate the planet if Navy SEAL Command Master Chief Robert Miller can't stop the menace from spreading.

Through more than 50 Koans - pleasingly paradoxical vignettes following the ancient Zen tradition - leading physicist Anthony Aguirre takes the listener across the world from West to East, and through ideas spanning the age, breadth, and depth of the Universe. Using these beguiling Koans (Could there be a civilization on a mote of dust? How much of your fate have you made?
