It's 2040. After decades of research, scientists of the European Union believe that they have at last conquered humankind's most pernicious foe: old age. For the first time, technology holds out the promise of not merely slowing the aging process but actually reversing it. The first subject for treatment is 78-year-old philanthropist Jeff Baker. After 18 months in a rejuvenation tank, Jeff emerges looking like a 20-year-old. And the change is more than skin deep. From his hair cells down to his DNA, Jeff is 20 - with a breadth of life experience.

But while possessing the wisdom of a septuagenarian at age 20 is one thing, raging testosterone is another, as Jeff soon discovers. Suddenly his oldest friends seem, well, old. Jeff's trophy wife looks better than she ever did. His teenage son, Tim, is more like a younger brother. And Tim's nubile girlfriend is a conquest too tempting to resist. Jeff's rejuvenated libido wreaks havoc on the lives of his friends and family, straining his relationship with Tim to the breaking point. It's as if youth is a drug, and Jeff is wasted on it. But if so, it's an addiction he has no interest in kicking.

Critics have compared the engrossing space operas of Peter F. Hamilton to the classic sagas of such SF giants as Isaac Asimov and Frank Herbert. But Hamilton's best-selling fiction - powered by a fearless imagination and world-class storytelling skills - has also earned him comparison to Tolstoy and Dickens. Hugely ambitious, wildly entertaining, philosophically stimulating: the novels of Peter F. Hamilton will change the way you think about science fiction.

Now, with Pandora's Star, he begins a new multi-volume adventure, one that promises to be his most mind-blowing yet. The year is 2380. The Intersolar Commonwealth, a sphere of stars some 400 light-years in diameter, contains more than 600 worlds, interconnected by a web of transport "tunnels" known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: Over 1,000 light-years away, a star...vanishes. It does not go supernova. It does not collapse into a black hole. It simply disappears.

Since the location is too distant to reach by wormhole, a faster-than-light starship, the Second Chance, is dispatched to learn what has occurred and whether it represents a threat. In command is Wilson Kime, a five-time rejuvenated ex-NASA pilot whose glory days are centuries behind him. Opposed to the mission are the Guardians of Selfhood, a cult that believes the human race is being manipulated by an alien entity they call the Starflyer.

Bradley Johansson, leader of the Guardians, warns of sabotage, fearing the Starflyer means to use the starship's mission for its own ends. Pursued by a Commonwealth special agent convinced the Guardians are crazy but dangerous, Johansson flees. But the danger is not averted. Aboard the Second Chance, Kime wonders if his crew has been infiltrated.

Soon enough, he will have other worries. A thousand light-years away, something truly incredible is waiting: a deadly discovery, the unleashing of which will threaten to destroy t...

Peter F. Hamilton's superbly imagined, cunningly plotted interstellar adventures are conceived on a staggeringly epic scale and filled with fully realized human and alien characters as complex as they are engaging. No mere world builder, Hamilton creates entire universes - and he does so with irresistible flair and intelligence.

His previous novel, the acclaimed Pandora's Star, introduced the Intersolar Commonwealth, a star-spanning civilization of the 24th century. Robust, peaceful, and confident, the Commonwealth dispatched a ship to investigate the mystery of a disappearing star, only to inadvertently unleash a predatory alien species that turned on its liberators, striking hard, fast, and utterly without mercy.

Coexistence is impossible with the technologically advanced aliens, who are genetically hardwired to exterminate all other forms of life. Twenty-three planets have already fallen to the invaders, with casualties in the hundreds of millions. And no one knows when or where the genocidal Prime will strike next.

Nor are the Prime the only threat. For more than 100 years, a shadowy cult, the Guardians of Selfhood, has warned that an alien with mind-control abilities impossible to detect or resist - the Starflyer - has secretly infiltrated the Commonwealth. Branded as terrorists, the Guardians and their leader, Bradley Johansson, have been hunted by relentless investigator Paula Myo. But now evidence suggests that the Guardians were right all along and that the Starflyer has placed agents in vital posts throughout the Commonwealth - agents who are now sabotaging the war effort. Is the Starflyer an ally of the Prime, or has it orchestrated a fight to the death between the two species for its own advantage?

Caught between two deadly enemies, one a brutal invader striking from without, the other a remorseless cancer killing from within, the fractious Commonwealth must unite as never before. This will be humanity's finest hour - or its last gasp.
