While hiding with Lord Owen, the Fae, and the human resistance, Aria questions everything she thought she understood. What are the Fae? Who is Aria herself? More than refuge, Aria needs answers. Despite the appeal of Dr. Bartok's talk of grace, the Empire's darkness threatens to overwhelm Aria as she wrestles with questions of sin, justice, and love. Colonel Grenidor has his own questions as he makes a new, powerful ally. How much can Edwin really be trusted? And what of the Slavemaster, who Edwin claims is an ally of the vampires opposing the Empire? Colonel Grenidor's research on the vampires has grown increasingly dangerous, with consequences for the Fae, the Empire, and supernatural entities on both sides of the conflict. Following Things Unseen, this second book in A Long-Forgotten Song is a riveting Christian fantasy that explores the depth of sin and the miracle of redemption.
