All magic has a price.

In an age where magic is still largely uncharted, Thonra, Sonja, and Ulrik Vinzler knew the risks better than most. All three took to their magical education quickly as children, but that seems a lifetime ago. A decade before Ulrik's sudden illness. A decade before his death.

The sisters made a pact. They'd chase any rumor, uncover any relic, and find a way to bring their brother back. The magic had to exist. If anyone could do it, the Vinzlers could. They wouldn't turn back without a solution, even if their own blood was the currency. Even if it took years of loneliness to find.
After years chasing folktales, a single rumor remains: Kepstadur Keep. This once-decadent port rots at the far edge of their home country, harboring memories of the lost or forgotten. With the help of a foreign mercenary, Sonja dares to pluck at the strands of Kepstadur’s magic, risking her life to understand its secrets.
But something malevolent waits for her there. If the castle proves itself more clever, Sonja could lose more than a brother to death’s soft voice.
 
No matter the outcome, magic will be paid.
