Mystery of the Amber Room (en Inglés) - Preston William Child

Thirty kilometers from the ruins of Chernobyl, something is waking up.

It has been dormant since 1945, locked inside the last surviving fragments of a masterpiece the world believes was lost forever. The Red Army unit that hid it never made it home. The Nazis who built it knew what it could do. And now an heir to the Third Reich has spent his life tracking it down.

He knows what lives in the amber. He knows what it does to a human mind. And he has already found his first test subject.

A billionaire inventor is taken. Tortured. Used as bait. The ransom is not money. It is the relic itself, delivered within forty-eight hours, or the German Chancellor dies and the Order of the Black Sun takes Europe by the throat.

Two people stand in their way. One of them is already infected. His thoughts obey him less with every passing hour. What he is becoming, the enemy built him to become.

The clock is running. The reactor is watching. And the Amber Room is about to open its eyes.

Perfect for fans of James Rollins, Clive Cussler, and Steve Berry.
