Missing for two hundred millennia, the legendary Iconians have returned, bringing with them the secret of interdimensional teleportation across vast interstellar distances. Awakened once more, their ancient Gateways are rewriting the map of the galaxy, and nowhere more than in the New Frontier.... A century ago, the imperial Thallonians separated two feuding alien races, depositing each of them on a new world safely distant from that of their ancestral enemies. Now, however, the Gateways have made it possible for the long dormant blood feud to begin anew. Captain Mackenzie Calhoun of the U.S.S. Excalibur and his partner, Captain Elizabeth Shelby of the U.S.S. Trident, find themselves fighting a losing battle to keep the horrific violence from escalating, even as they gradually realize the catastrophic danger posed by the Gateways themselves!

Once they moved from world to world in a single step, through innumerable doors that spanned the galaxy. They were masters of space, and to those who feared them, they were demons of air and darkness. But long ago they left their empire and their miraculous technology behind. Now someone has found the key to it, and all those doors have been þung open. GATEWAYS DEMONS OF AIR AND DARKNESS A world near Deep Space 9™, threatened with destruction from the distant Delta Quadrant, becomes the focus of a massive rescue effort as Colonel Kira Nerys, her crew, and some unexpected allies Þght to avert disaster on a planetary scale. Meanwhile, as Lieutenant Nog and Ensign Thirishar ch'Thane search for a way to shut down the spatial portals forever, Quark becomes involved in a dangerous game that could determine, once and for all, who will control the Gateways.

More than 200,000 years ago, the ancient Iconians created a network of interdimensional Gateways providing instantaneous transportation across unimaginable distances. Once known as the "Demons of Air and Darkness," the Iconians mysteriously vanished many millennia ago, never to return -- or so it was believed. GATEWAYS DOORS INTO CHAOS Summoned to an emergency brieÞng at Starþeet Headquarters, Captain Jean-Luc Picard is stunned to discover that the legendary Iconians have returned at last, and are offering to sell the secrets of their advanced technology to the Federation. To prove their sincerity, they have reactivated their long-abandoned Gateways, but the results have been strife and chaos throughout the entire Alpha Quadrant. Now Picard and his crew must contend with feuding Klingons and Romulans as the captain seeks to discover the sinister truth behind the Iconians' unexpected rebirth!

"Created by the incalculably ancient Iconians, whose transcendent technology is quantum levels beyond that of the Federation and its allies, the Gateways offer instantaneous transport across unimaginable distances. Throughout the known galaxy, from Deep Space Nine(TM) to the New Frontier, from the Delta Quadrant to the bridge of the Starship Enterprise (TM), the sudden reactivation of the Gateways has destabilized interstellar relations between planets and cultures previously separated by countless light-years. Starfleet's finest have coped with the crisis as best they can, but circumstances have forced several valiant commanders to leap through separate Gateways into the unknown. Captain James T. Kirk of the original Starship Enterprise Captain Jean-Luc Picard of Star Trek: The Next Generation Colonel Kira Nerys of Deep Space Nine Captain Kathryn Janeway of the U.S.S. Voyager (TM) Captains Calhoun and Shelby of Star Trek : New Frontier Commander Nick Keller of the U.S.S. Challenger All of these heroes, for their own reasons, have taken the ultimate gamble: hurling themselves personally through a Gateway without any knowledge or forewarning of what lay beyond. Each must face their own unique challenge, struggling to find a way back to the ships and homes they left behind. And waiting behind at least one of the Gateways are the ageless Iconians themselves, the primordial architects of the mysterious portals causing chaos throughout the Milky Way galaxy. Where did they disappear to, many long eons ago, and what do they want now? The answer lies on the other side.... What Lay Beyond brings the Gateways saga to a spectacular finish, in an all-star collaboration by six popular, bestselling Star Trek authors. Among them, Diane Carey, Peter David, Keith R.A. Decandido, Christie Golden, Robert Greenberger, and Susan Wright have written dozens of Star Trek novels. This is their first mega-collaboration."
