In the Kingdom of Shade, not even the dead may rest.

The undead rise, day after day, century after century, and they are delivered back to their peaceful graves by one group: the Hunters of Noelictus.

Slaying undead is an endless task, but one Hunter Haeight has aspired to all her life. She joins Noelictus' Hunter's Guild and swiftly works her way up the ranks, slaying zombies, skeletons, and ghouls with dedication and zeal.

However, there is a rot within the Kingdom of Shade, and Haeight's aspirations turn into doubts as she finds a web of conspiracies in the capital, Menorome. The Hunters there are off—something is afoot. It is a bewildering, overwhelming place for new Hunters, as well as the fourth Princess of Calanfer, Seraphel du Marquin, who has arrived for her marriage, unhappy and alone.

In Menorome, the streets shine with lights to ward off the darkness. For a Hunter, there is little rest or time. For a Princess, there is little to enjoy or look forward to. However, in the depths of despair, there is always the Singer. There is always a song. The Singer of Afiele has come to the city, same as the Princess and the Hunter, and all their fates will soon be intertwined in a greater web of secrets than any of them dreamed of.
