Book excerpt: "A classic, breathtaking adventure brimful of dangerous magic and clever politics. A book that will thrill and delight any fantasy fan."―Tasha Suri, author of The Jasmine Throne In this fresh epic fantasy bursting with intrigue and ambition, questioned loyalties, and broken magic, one woman will either save an entire continent or bring about its downfall. "Guard the tower, ward the stone. Find your answers writ in bone. Keep your trust through wits or war--nothing must unseal the door." Deep within Gloamingard Castle lies a black tower. Sealed by magic, it guards a dangerous secret that has been contained for thousands of years. As Warden, Ryxander knows the warning passed down through generations: nothing must unseal the Door. But one impetuous decision will leave her with blood on her hands--and unleash a threat that could doom the world to fall to darkness.
