The Obsidian Tower

One woman will either save an entire continent or completely destroy it in a fresh epic fantasy bursting with intrigue and ambition, questioned loyalties, and broken magic. "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.
