Here's the blurb:
Two thousand years ago, the Born Queen defeated the Skasloi lords, freeing humans from the bitter yoke of slavery. But now monstrous creatures roam the land—and destinies become inextricably entangled in a drama of power and seduction. The king’s woodsman, a rebellious girl, a young priest, a roguish adventurer, and a young man made suddenly into a knight—all face malevolent forces that shake the foundations of the kingdom, even as the Briar King, legendary harbinger of death, awakens from his slumber. At the heart of this many-layered tale is Anne Dare, youngest daughter of the royal family . . . upon whom the fate of her world may depend.
