The Obsidian Tower (Rooks and Ruin, 1) [Caruso, Melissa]

Ebook

One woman will either save an entire continent or completely destroy it in  a captivating 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  unreal  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.
