    When an ambasador from the far-off Tamul Empire begged for help, Sparhawk, Ehlana's champion and Prince Consort, was the Emperor's last hope. For surely the knight who had killed the evil God Azash could prevail against the terror in Tamul. But waiting for him was a glittering court seething with corruption, treachery--and the greatest danger Sparhawk would ever face!

    Blending archaeological fact and legend, the myths of the gods and the feats of heroes, Marion Zimmer Bradley breathes new life into the classic tale of the Trojan War-reinventing larger-than-life figures as living people engaged in a desperate struggle that dooms both the victors and the vanquished, their fate seen through the eyes of Kassandra-priestess, princess, and passionate woman with the spirit of a warrior.

    It was a time of Decision.The bureaucrats of Earth, the stark pioneers of "terraformed" Mars, and the proud gill-altered rulers of Venus were torn between two techno-religions - one offering the certainty of eternal life; and the other, a far-flung destiny among the stars.

    After drinking way too much champagne, she performed, of all crazy things, a goddess-summoning ritual, hoping that it would somehow make her life a little less ordinary...but she never believed the spell would actually work.When her military plane crashes into the ocean, CC's mission overseas takes an unexpected turn. She awakens to find herself in a legendary time and place where magic rules the land—occupying the body of the mythic mermaid Undine. But there is danger in the waters and the goddess Gaea turns this modern, military gal into a beautiful damsel so that she can seek shelter on land.CC is soon rescued (literally) by a knight in shining armor. She should be falling in love with this dream-come-true, but instead she aches for the sea and Dylan, the sexy merman who has stolen her heart.

    The great winged Lion stares over a Venice where magic thrives. The rich Venetian Republic is a bastion of independence and tolerance. Perhaps for that reason, it is also corrupt, and rotten with intrigue.But for the young brothers Marco and Benito Valdosta, vagabond and thief, Venice is simply--home. They have no idea that they stand at the center of the city's coming struggle for its very life. They know nothing of the powerful forces moving in the background. They have barely heard of Chernobog, demon-lord of the North, who is shifting his pawns to attack Venice in order to cut into the underbelly of the Holy Roman Empire. All Marco and Benito know is that they're hungry and in dangerous company: Katerina the smuggler, Caesare the sell-sword, Montagnard assassins, church inquisitors, militant Knights of the Holy Trinity, Dottore Marina the Strega mage... and Maria. Maria might be an honest canaler, but she had the hottest temper a boy could find. Yet among the dark waters of the canals lurk far worse dangers than a hot-tempered girl. Chernobog has set a monster loose to wreak havoc on the city. Magic, murder and evil are all at work to pull Venice down. Fanatical monks seek to root out true witchcraft with fire and sword. Steel-clad Teutonic knights, wealth traders, church dignitaries and great Princes fight and plot for control of the jewel of the Mediterranean. And somehow all of these, from thieves to mages to princes, must gather around Marco and his brother Benito, under the shadow of the great winged lion of Venice.

And they possess an ancient magic their would-be conquerors have long discounted--a powerful sorcery that threatens to claim Nevare Burvelle's soul and devastate his world once the Dark Evening brings the carnival to Old Thares.

    King Cador knew this once, but now the land has turned from him, calling instead to his three children. Riva can cure others, but can’t seem to heal her own deep scars.

And Sinne dreams of seeing the world, of finding adventure.All three fear a life of confinement within the walls of the hold, their people’s last bastion of strength against the invading Saxons.

    God, demon, monster, and sorcerer alike plot to regain what was theirs.1913, Salem, Massachusetts – Sarah Engelmann’s life is full of friends, books, and avoiding the pressure to choose a husband, until an ominous vision and the haunting call of an otherworldly trumpet shake her.

And when she sees the murdered boy moving through the crowd at an amusement park, Sarah is thrust into a dark battle she does not understand. With the help of Alex, an attractive Greek immigrant who knows a startling amount about the undead, Sarah sets out to uncover the truth. Their quest takes them to the factory mills of Salem, on a midnight boat ride to spy on an eerie coastal lair, and back, unexpectedly, to their own homes. What can Alex’s elderly, vampire-hunting grandfather and Sarah’s own rabbi father tell them? And what do Sarah’s continuing visions reveal?No less than Gabriel’s Trumpet, the tool that will announce the End of Days, is at stake, and the forces that have banded to recover it include a 900 year-old vampire, a trio of disgruntled Egyptian gods, and a demon-loving Puritan minister. At the center of this swirling cast is Sarah, who must fight a millennia-old battle against unspeakable forces, knowing the ultimate prize might be herself.

    An innocent pup of the Degnan Packstead, Marika thought it was just a tale to frighten the young. Then the Grauken-possessed, cannibalistic nomads swept down from the far north -- and the winter of death began.Marika's pack now has to fight for its life -- even if it means calling upon the treacherous witchlike Silth who can slay by mind alone.

Or will she become something far greater than the Silth, something fearfully whispered of only in legends... Doomstalker.

    But when he meets the hauntingly pale, steely-eyed Joshua York, he is certain. For York doesn’t care that the icy winter of 1857 has wiped out all but one of Marsh’s dilapidated fleet. Nor does he care that he won’t earn back his investment in a decade. York has his own reasons for wanting to traverse the powerful Mississippi. And they are to be none of Marsh’s concern—no matter how bizarre, arbitrary, or capricious his actions may prove. Marsh meant to turn down York’s offer. It was too full of secrets that spelled danger. But the promise of both gold and a grand new boat that could make history crushed his resolve—coupled with the terrible force of York’s mesmerizing gaze. Not until the maiden voyage of his new sidewheeler Fevre Dream would Marsh realize he had joined a mission both more sinister, and perhaps more noble, than his most fantastic nightmare...and mankind’s most impossible dream. Here is the spellbinding tale of a vampire’s quest to unite his race with humanity, of a garrulous riverman’s dream of immortality, and of the undying legends of the steamboat era and a majestic, ancient river.

    When a man learns his language, Dar finally gets the chance to tell his story. He begins his tale as a young man, and how he went down to the human underworld and got hold of the immortality meant for humans, long before Julius Caesar came into the Celtic lands; how he sailed West to America with the Irish monks searching for the Paradise of the Saints; and how he continuously went down into the land of the dead and returned. Through his adventures in Ka, the realm of Crows, and around the world, he found secrets that could change the humans’ entire way of life—and now may be the time to finally reveal them.

    After I saw my little brother’s death but failed to stop it, my parents abandoned me to a juvenile detention facility. I don’t let people touch me anymore. Not my fingertips, not my skin, not my heart. I make my own clothes by stitching together the donations we get; usually a bunch of crap that fits like a parachute. My sweater is a patchwork of different shades of inky, dark squares. I make plain gray skirts that hang to my knees, with cute or funny T-shirts sewed in. They clash ironically with my unsmiling face. My Allstar high-tops are black and frayed, like my soul. I also wear a chunk of brightly colored legos around my neck. My little brother was working on it the day he died. The day I failed to save him. It’s unfinished, so I’ll never know what it was meant to be. Most days, I just try to get by. But then I got a visit from a cute guy, who tricked me into giving up my secrets. He said I was special. That he needed me. For a while, I believed him. But once I found out what I could really do, I learned everybody wanted the power I possessed. The power to destroy deities. To kill gods. To end the world... or to save it. My heart is torn, and those I loved most betrayed me. I'm trying so hard to do what's right, but nobody can tell me what that is anymore, and the moral boundaries I'd always let define my life have been shattered. Whose rules should I obey now? Or do I have to make my own? The Scarlet Thread is a dark fantasy for fans of Greek mythology and Gothic romance. Fans of Fallen and Percy Jackson will be captivated by this mashup of fallen angels and forgotten gods.
