Resonanz

Lübeck, 1372: In a flooded cellar, the healer Runa discovers a silvery substance that responds to warmth, breath and human closeness. When her daughter comes into contact with it, a story begins whose consequences stretch across centuries.

In the present, a badly injured man is rescued from a secret laboratory. His body heals faster than medicine should allow. At the same time, systems fall out of rhythm, old records surface, and a powerful order will stop at nothing to bring under its control a knowledge that was never theirs.

At the centre stands Johann Koch. His past has been altered, his name replaced, and his memory buried under foreign identities. Yet something in him recognises connections before they become visible. Something leads him back to Hamburg and Lübeck, to his family and to the origin of a secret.

Who is Johann really? What has his family preserved for generations? Why were people killed, documents hidden and memories manipulated? And what happens when human beings try to master a force that responds to them?
