King Ludwig II of Bavaria was an enigmatic figure who was deposed in 1886, mysteriously drowning three days later. Eccentric to the point of madness, history tells us that in the years before he died, Ludwig engaged in a worldwide search for a new kingdom --- a place he could retreat into and rule as he wished. But a question remains: Did he succeed? Enter Cotton Malone. After many months, Malone’s protégé, Luke Daniels, has managed to infiltrate a renegade group intent on winning Bavarian independence from Germany. In a race across Bavaria for clues hidden in Ludwig’s three fairy-tale castles --- Neuschwanstein, Linderhof and Herrenchiemsee --- Malone and Daniels battle an ever-growing list of deadly adversaries, all intent on finding the last kingdom.
