What is the worth of your spirit?

In the world of Awya, where life is scattered across isles in a seemingly endless ocean of black liquid, the Isle of Winder is home to uymns whose primary trade is agriculture and flower cultivation. Here, an umyn boy by the name of Amory Demshen becomes obsessed with Tempertime Cemetery—a collection of portals powered by spirits that link the isles of Awya together, and a place forbidden to those without proper training and knowledge.

Amory disobeys the laws and his mother, sacrificing the qualities of youth and the virtues of his upbringing to pursue a selfish adventure connived by a hidden, sinister force. Unnerving truths and perilous consequences await as Amory—equipped with an authoritative jar, a chest of bewitching cards, and a flying stone slab—plunges into the darkness of the spirit collectors.

Will Amory learn the worth of a spirit in time to save his own?
