Halfblood Chronicles by Mercedes Lackey

Two masters of epic fantasy have combined in this brilliant collaboration to create a rousing tale of the sort that becomes an instant favorite. This is the story of Shana, a halfbreed born of the forbidden union of an Elvenlord father and a human mother. Her exiled mother dead, she was rescued and raised by dragons, a proud, ancient race who existed unbeknownst to elven or humankind. From birth, Shana was the embodiment of the Prophecy that the all-powerful Elvenlords feared. Her destiny is the enthralling adventure of a lifetime.  The powerful magic of ruthless Elvenlord masters has for centuries rules the world. Even Shana, the legendary Elvenbane prophesied to deliver the oppressed into freedom, is helpless before such power. She and her ragtag band of outcasts, half-blood wizards, escaped human slaves, and free-thinking dragons have gained only a token victory against the mighty lords.  Only the long-forgotten Iron People, a band of human nomads, have escaped the tyranny of the reigning wizards. How have they survived through the centuries?  As the winds of change sweep the world, and as tensions seething beneath the surface of Elven society threaten to break into open revolt. Shana meets the ancient tribe. Could an age-old secret free Shana and her people…or will its discovery call down their doom.  In this long-awaited new novel in The Halfblood Chronicles, fantasy greats Norton and Lackey tell the enthralling story of the reclusive elvenlord Kyrtian, who emerges as a hero in a world torn by politics and war. When his cousin, Aelmarkin, tries to prove that Kyrtian is unfit to run his estate, the plan backfires, and soon Kyrtian, who doesn’t share the venal, greedy nature of his cousin, finds himself with more power than he ever wanted.  Like his father before him, Kyrtian has always treated the humans on his estate like servants, instead of enslaving them as other elvenlords do. His father’s legacy also leads Kyrtian to learn ancient military skills long since lost to elvenkind through the carelessness of the elvenlords. Kyrtian’s rediscovered knowledge piques the interest of the current elvenlords, and soon Kyrtian finds himself appointed the new commander of the army, to the relief of his ruling peers.  For the sons of the most powerful elvenlords, the Young Lords, have rebelled against their fathers and are waging war. But by taking advantage of both the privileges of his new command and the help of some unexpected new friends, Kyrtian finally gains the resources to embark on his own, personal quest–resuming his father’s search for the Great Portal, the magical doorway through which the original elvenlords entered this world.  As war rages between some sons and fathers, Kyrtian searches desperately for his own lost father, hoping to uncover not only the mystery of his disappearance, but also the secret behind the origin of elvenkind.
