King's Dragon Crown of Stars #1

From one of Fantasy's shining new lights comes this first volume in a magnificent epic set in a richly realized land and culture where bloody rebellion may soon destroy the kingdom, while sorcerous confrontations and the secret workings of an otherworldly race could transform the very land into a place in which no mortal was ever meant to dwell.
It begins with the threat of civil war. For though King Henry still holds the crown of Wendar, his reign has long been contested by his sister Sabella. There are many eager to flock to her banner, whether from their belief in her cause or the hope of personal gain. And there are ways to bring others under her command, methods to make even the most unwilling lord into a weapon pointed at the very heart of Henry's realm.
Torn by internal strife, Wendar also faces deadly raids from the north by an inhuman race, the Eika, and from the east by the "winged" riders, the Qumans. And terrifying portents are being seen by many; old ruins restored to life under the light of the full moon and peopled by the long vanished Lost Ones; dark spirits walking the land in broad daylight.
And suddenly two innocents - Alain, a young man who may find his future in a vision granted by the Lady of Battles, and Liath, a young woman with the power to change the course of history if she can only learn to master her fear and seize what is rightfully hers - are about to be thrust into the midst of the conflict.
