Salt to the Sea is a 2016 historical fiction young adult novel by Ruta Sepetys. It tells the story of four individuals in World War II who make their way to the ill-fated MV "Wilhelm Gustloff". The story also touches on the disappearance of The Amber Room, a work of art stolen by the Nazis that has never been recovered. Using only the above description and what you know about the world, "Nobody knows who currently possesses The Amber Room." is definitely correct, incorrect, or inconclusive?
