Young wizards Kit Rodriguez and Nita Callahan manage to wangle their way onto an elite team sent to investigate the mysterious, long-sought "message in a bottle" that holds the first clues to the secrets of the ancient Martian race.

They call themselves Rihannsu – the Declared. To the Federation, they are the Romulans. By any name they are adversaries as formidable as they are inscrutable. Self-exiled from Vulcan in ages past, they retain an ancient martial philosophy and a code of conduct that has sustained them through centuries of hardship, warfare, and thwarted ambition. Now their empire is gearing for war once again. Armed with the revolutionary Sunseed technology, which can destabilize entire stars, a Romulan vessel is warping toward the heart of the Federation. Its target: Earth's sun. But this offensive comes at a perilous time, as a growing number of Romulan worlds are joining a revolution – one led by the renegade Commander Ael t'Rllaillieu of the warbird Bloodwing, with the aid of Captain James T. Kirk of the Starship Enterprise™ and the Hamalki physicist K's't'lk, the Federation's foremost authority on Sunseed technology. As the threat to Earth looms ever larger, Bloodwing and Enterprise lead an armada toward the Romulan homeworld for a final reckoning that will decide the future of the Rihannsu people.

Rihannsu is a Star Trek: The Original Series miniseries by Diane Duane with Peter Morwood. The first two novels—My Enemy, My Ally and The Romulan Way—were originally published as stand-alone (though interconnected) adventures. When a follow-up duology was published in 2000, the first two were reprinted under the umbrella title Rihannsu. In December 2006, the fifth novel, The Empty Chair, was published, as was an omnibus collection of the four previous novels titled The Bloodwing Voyages. My Enemy, My Ally and The Romulan Way were revised for the omnibus, with dates and character ranks shifting to be consistent with the later novels. Also, Honor Blade was merged into Swordhunt for the omnibus.

Vulcan: linchpin member of the United Federation of Planets. Home to a civilization dedicated to o'thia, the ruling ethic of pure logic. But it was not always so; thousands of years before, Vulcans were a violent, warlike race, with tempers surpassed only by the planet's hot, arid sands. The philosopher Surak would show his people another way, teach them to reject their emotions and embrace logic and knowledge. The Vulcans would evolve and prosper, eventually exploring the stars and attaining further enlightenment as they encountered other cultures. In the twenty-third century, Commander Spock, Captain Kirk, and the USS Enterprise are summoned to Vulcan when its people consider seceding from the Federation and returning to their isolationist ways. Vulcan's savage history becomes fully revealed as Spock, his father Sarek, and Kirk work to preserve the planet's future from anti-Terran factions with hidden agendas. The crisis is twofold for the half-Human Spock – should Vulcan secede, he will be required to resign from Starfleet and return home, or forever sever ties with his homeworld. Years later, a decades-old plot to destroy the Federation from within forces Ambassador Sarek from the bedside of his dying wife, Amanda. The ambassador's decision widens the long-standing rift between himself and Spock at a time when they must pool their resources together. While the Enterprise crew contends with Romulans, Klingons, and the mysterious Freelans, Sarek's only comfort comes from reading Amanda's journals, which reveal more about his Human spouse, his son, and himself than he ever realized. This edition focusing on Vulcan culture includes the New York Times bestselling novels Spock's World, by Diane Duane, and Sarek, by A.C. Crispin.

Juvenile fiction. Captain Kirk unites with his old enemy Ael t' Rlailiiu, a Romulan commander, to destroy the laboratory that is genetically harnessing the mind power of Vulcans.

At last, the United Federation of Planets and the Romulan Star Empire have agreed to meet on neutral ground to attempt to resolve the tangle of intrigue and conspiracy that began with the hijacking of the U.S.S. Intrepid many years ago -- but the meeting may be as dangerous as the war they hope to avoid. As a show of good faith, the crew of the legendary Starship Enterprise has been ordered to attend the talks. In their informal charge is Romulan renegade Ael, the wanted fugitive who, with Kirk, served as a catalyst of the current troubles. Kirk must represent the interests of the Federation first and foremost, but the best approach to an agreement remains muddled in the ever-shifting Romulan order. And the visiting Romulan party is as fractious and divided as their troubled world. Among the Romulan nobles in attendance are the hero and popular Senator Arrhae, who secretly helped rescue Dr. Leonard McCoy from a Romulan execution, and the very men and women who put McCoy on trial for treason -- and tried to carry out the sentence. As Kirk and crew attempt to renegotiate a delicate peace, and Romulans attempt to restore their tarnished honor, it becomes increasingly apparent that their only course of action is to prepare for war!

The sword was the ultimate symbol of Romulan power, tradition, and pride. It lay in the Senate Chamber of the Romulan Star Empire, revered and untouched for centuries, until the day Dr. Leonard McCoy was tried for treason -- and both were stolen during a daring attack on Romulus itself. Now, to avenge that insult and save face in the eyes of their deadly enemies, the Empire must recover the sword at any cost. Their envoys to the Federation demand the return of the sword and the extradition of the Romulan renegades who aided the Starship Enterprise in McCoy's escape. If diplomacy fails, the Romulans will trap the Klingons and the Federation in open war. In such dangerous times, the Starship Enterprise is assigned the most valuable -- and volatile -- element of all: the fugitive Ael, her stolen Bird-of-Prey • Bloodwing, and the sword they carry. Ael will undoubtedly attempt to use ship and sword to foil her enemies and play her hand in the dangerous game that she's begun. But she will do it all under the watchful eyes of James T. Kirk, the Federation starship captain who knows her dangerously well....

'"I am Spock… I hold the rank of commander in the Starfleet of the United Federation of Planets; I serve as first officer of the starship Enterprise. I am the son of two worlds. Of Earth, whose history is an open book… and of Vulcan, whose secrets have lain hidden beneath its burning sands… Until now..." It is the twenty-third century. On the planet Vulcan, a crisis of unprecedented proportions has caused the convocation of the planet's ruling council - and summoned the USS Enterprise from halfway across the galaxy, to bring Vulcan's most famous son home in its hour of need. As Commander Spock, his father Sarek, and Captain James T. Kirk struggle to preserve the very future of the Federation, the innermost secrets of the planet Vulcan are laid before us, from its beginnings millions of years ago to its savage prehistory, from merciless tribal warfare to medieval court intrigue, from the exploration of space to the development of c'thia - the ruling ethic of logic. And Spock - torn between his duty to Starfleet and the unbreakable ties that bind him to Vulcan - must find a way to reconcile both his own inner conflict and the external dilemma his planet faces...lest the Federation itself be ripped asunder.
