The Sun Furnace

Description

Three books appear after the rain.

No title. No sender. No explanation.

Yet hidden within their pages are clues to a mystery that began with impossible lights over Aarhus Bay.

For Anneli Hartman and Mr. Winter, the trail leads west of Aarhus, towards an abandoned gravel pit.

There, concealed among the remnants of a forgotten experiment, stands an extraordinary optical installation.

The Sun Furnace.

Its intricate mechanisms may hold the answers to everything they have discovered. The coded signals. The hidden railway. The dangerous machinery beneath the cliffs.

But the closer they come to understanding the system, the more disturbing the questions become.

Who first controlled these inventions?

What really happened to the people who worked with them?

And why has so much effort been spent keeping the truth out of sight?

Someone knows the answers. And someone still wants control.

Anneli has learned to recognise the smallest discrepancies — the details that others overlook, the observations that change the meaning of everything around them.

But even her gift for uncovering patterns may not be enough.

Because understanding the Sun Furnace is only the beginning.

The machinery is dangerous. The evidence is incomplete. And the consequences of another mistake could reach far beyond the abandoned site.

For Mr. Winter, the investigation also brings questions that can no longer be avoided. His knowledge of the past may be indispensable — but trust demands more than knowing when to speak.

Together, Anneli and Winter must face a challenge unlike any they have encountered.

Can they uncover the truth without repeating the very mistakes that made it so dangerous?

And when the final connections emerge, will they have the courage to act on what they discover?

Every signal has led them here.

The Sun Furnace is the third and concluding novel in The Hidden Lines of Light, an atmospheric historical mystery trilogy set in an imagined Denmark of coded signals, ingenious optical inventions, gothic atmosphere and dangerous secrets.

For readers who enjoy intelligent mysteries, determined heroines, enigmatic partnerships and discoveries that transform everything that came before.

The mysteries that began in The Light Over the Bay and continued in The Light Beneath the Cliff reach their conclusion here.

Read the trilogy in order: Book One → Book Two → Book Three.
