Every year, the people of Borne come to Sunder to celebrate The Parse, an annual tradition where anyone wanting to get married and have children must participate.
This year, Innis’ uncle is forcing him to compete.
East is heartbroken when he finds out, because it could mean losing the boy he loves. Enraged, he decides to enter The Parse as well, hoping to keep Innis, but he needs a partner.
A chance meeting with Samone, a girl cursed to turn into a siren every day, offers him exactly what he needs. Her curse can be revoked by a boy, making East an opportunity of a lifetime for her.
Their goal leads them to keep each other’s secrets, because if the truth gets out about who they are, Sunder would be merciless with them.
